Chapter 5-Countif(s)/Sumif(s)/Averageif(s)/Large/Small/Rank THE COUNTIF FUNCTION Thus far functions have been used to answer questions like “What is the average grade?” or “What is the maximum grade?” But how can we answer the question “How many phone providers are there on a type B network?” To answer this question we will need to look at the spreadsheet in Figure 7 and count the number of cells containing the letter B in the range B5:B8. Service Ratings Network Type Total Possible points H B H B BT&T Blue Phone Horizen Spuce Average East Midwest South West Total 100 100 100 100 400 81 53 51 90 90 80 70 88 77 91 75 86 55 90 82 345 265 302 247 69 80 83 78 Percent Figure 1 The fact that something is being counted may imply that a COUNT function can be used. However, the COUNT function can only count the number of numerical values in a list, which is not what is needed here. There is even a COUNTA function that can count the number of numerical and text values in a list, but this still does not capture the process we go through to count only type B network providers. What we really need to do is find a way to count items in a list that meet a specified criterion. THE COUNTIF FUNCTION SYNTAX: The COUNTIF Function is designed to count the number of items in a range that meet a user specified criterion. The syntax of the function is as follows: =COUNTIF(range,criteria) This function has two arguments: a continuous cell range and a criterion. The COUNTIF function will only work as intended if the correct number of arguments are entered in the correct order. The COUNTIF function is further differentiated from the COUNT function in that it works equally well with text labels as with values so that it will be possible to count the number of B’s in a range of cells. The valid methods of specifying a criterion in this function include but are not limited to the following: Chapter 5 Page 1 Chapter 5-Countif(s)/Sumif(s)/Averageif(s)/Large/Small/Rank Criteria Type: Example: Using a specific text value =COUNTIF(B2:C4,“xyz”) will find all instances of the text string xyz (caps or small letters) in the continuous range B2 through C4. Using a specific numerical value =COUNTIF(B2:B10,0) will find all instances of the value zero in the continuous column range from B2 to B10. Using a cell reference =COUNTIF(B2:B10,B2) will find all instances of the value found in cell B2 in the continuous range B2 to B10. Note that cell B2 may contain text, a numerical value or a Boolean value. Using a relational expression =COUNTIF(B2:B10,“>0”) will find all instances of values that are greater than zero in the continuous range B2 to B10. Notice the special syntax here. It is unusual to use quotes in numerical expressions. The COUNTIF function is one of the few exceptions in Excel where quotes are used except to indicate text. (>,<, >=,<=,<>) Using a specific Boolean =COUNTIF(B2:F2,TRUE) will find all instances of the value value TRUE in the continuous range from B2 to F2. Notice that TRUE does not have quotes since it is a Boolean value and not a label. (Boolean values will be introduced in the next chapter.) This function can only accommodate a single continuous range argument (one or two dimensional range). A list of cell references and/or non-continuous ranges cannot be interpreted by this function since the first time it encounters the comma delimiter it assumes a criterion will follow, not additional ranges. =COUNTIF(B2:B10,C2:C10, “x”) has no meaning since the computer would assume that C2:C10 is a criterion that it is unable to evaluate. Remember, Excel treats capital and small letters as the same. So specifying “X” is the same as specifying “x”. This is not the case for all software packages. USING THE COUNTIF FUNCTION: Each of the examples below further illustrates the different types of criteria that a COUNTIF Service Ratings Network Type Total Possible points H B H B BT&T Blue Phone Horizen Spuce Average East Midwest South West Total 100 100 100 100 400 81 53 51 90 90 80 70 88 77 91 75 86 55 90 82 345 265 302 247 69 80 83 78 Percent Figure 2 Chapter 5 Page 2 Chapter 5-Countif(s)/Sumif(s)/Averageif(s)/Large/Small/Rank function can use. Using Figure 8 and the 3-step process, solve the following problems. Question #1: Write an Excel formula to determine the number of rating scores for all providers and all regions that received an unacceptable rating. The minimum acceptable rating is 80. What value will result? The question asks for the number of scores below 80 for all providers and regions. To answer this question, count the number of scores in the range C5:F8 that are less than 80. The COUNTIF function can be used to count the number of cells that meet a criterion. The first argument is the range, which in this case is C5:F8. The criterion is less than 80. Hence, the formula would be =COUNTIF(C5:F8, “<80”). The resulting value is 5, since five of the ratings listed are below 80. Note that this function also ignores cells that are blank. Since the formula is not copied, all cell references should be left as relative. Should a cell reference be used instead of the value 80 so that if the acceptable score changes so would the result of the function? In general it is always better to reference a value, so if it changes it needs to be modified in just one place. However, the COUNTIF function algorithm is not setup to recognize a cell reference together with a relational operator. It will accept a simple cell reference (E1) or a relational operator (“<80”) but not both (“<E1”) unless additional special characters are added. Question #2: Write an Excel formula in cell B12 (not shown) to determine the number of networks of either type B or type Z. To solve this problem without a computer look for the data that specifies each provider’s network type (column B) and then count the number that meets the criteria, which is either a B or Z. The COUNTIF function can only count the number of entries that meet one single criterion, not two. However, the number of B’s can first be counted and then added to the number of Z’s: =COUNTIF(B3:B7,“B”)+COUNTIF(B3:B7,“Z”) Since this formula is not copied, no absolute cell referencing is required. A MORE COMPLEX EXAMPLE: Consider the example in Figure 9 which contains a slightly modified version of the rating spreadsheet including a Summary by network type in rows 11 through 13. A 1 B C D E F G Service Ratings 2 Network Type 3 Total Possible points East Midwest South 100 100 100 West 100 Total 400 86 55 90 82 345 265 302 247 4 5 BT&T 6 Blue Phone 7 Horizen 8 Spuce H B H B 81 53 51 90 90 80 70 88 77 91 75 9 10 11 12 13 # in Total Total Total Total Total - all Summary Network East Midwest South West regions H 2 132 160 179 176 647 B 2 143 80 152 137 512 Z 0 0 0 0 0 0 Figure 3 Chapter 5 Page 3 Chapter 5-Countif(s)/Sumif(s)/Averageif(s)/Large/Small/Rank What formula will be needed in cell B11 to determine the number of networks of type H? How can this formula be written so that it can be copied down the column to automatically calculate this value for type B networks and type Z networks? Solve using our 3-step process as follows: To determine the number of type H networks, count the number of occurrences of “H” in the Network Type column in the range B5:B8. A COUNTIF function counts the number of values that meet a criterion. The range of cells the criterion will be compared to is B5:B8 and the criterion is “H”, so the corresponding formula will be =COUNTIF(B5:B8,“H”). Consider copying the formula down the column to cell B12. The formula used in cell B12 should count the number of type B networks. If the formula in cell B11, =COUNTIF(B5:B8,“H”), is copied relatively the new formula will be =COUNTIF(B6:B9,“H”). o Notice that the range argument will change by one cell; the new range excludes the data in cell B5 and includes the blank cell in row 9. This range should remain unchanged by adding absolute cell referencing to the rows. Now the resulting formula would be =COUNTIF(B$5:B$8,“H”). o Although the range is now correct, this formula as written still adds the number of type H networks instead of the number of type B networks. One solution is to use a cell reference to specify the criteria instead of placing an ‘H’ directly into the formula. The reference A11 can be used, since cell A11 contains the value “H”. When the formula =COUNTIF(B$5:B$8,A11) is copied down, the reference will change to A12, corresponding to the value “B” as desired. THE SUMIF FUNCTION Again consider the worksheet in Figure 9. In the summary, the total rating points for each network type and region appear in cells C11:G13. Calculating these values using the tools we’ve learned thus far would require writing a different formula for each row. This solution would be tedious and would require updating if the network types were to change in the future. The process used to calculate the total for each cell is essentially the same - in each region the rating points are added for only companies that have the corresponding network type. Ideally, this process should be automated to sum values that meet a specific criterion. Chapter 5 Page 4 Chapter 5-Countif(s)/Sumif(s)/Averageif(s)/Large/Small/Rank THE SUMIF FUNCTION SYNTAX: The SUMIF Function is designed to add all values in a range that meet a specified criterion. Its syntax is as follows: =SUMIF(criteria_range,criteria,sum_range) The SUMIF function has three arguments: (1) The criteria range is the range of values to be compared against the criterion. (2) The criteria argument is the specific value (text, numerical, Boolean) or relational expression to compare each value in the criteria range to. (3) The sum range is the corresponding range of cells to sum if the criterion has been met. If this range is the same as the criteria range then it may be omitted. This function works almost identically to the COUNTIF function in that its ranges must be continuous and the criteria may be a value, cell reference, or relational expression. The same syntactical rules apply for specifying criteria. USING THE SUMIF FUNCTION: Before tackling the question at the beginning of this section, consider some simple examples of the SUMIF function using the spreadsheet in Figure 10 A 1 B C D E F G Service Ratings 2 Network Type 3 Total Possible points East Midwest South 100 100 100 West 100 Total 400 86 55 90 82 345 265 302 247 4 5 BT&T 6 Blue Phone 7 Horizen 8 Spuce H B H B 81 53 51 90 90 80 70 88 77 91 75 9 10 11 12 13 # in Total Total Total Total Total - all Summary Network East Midwest South West regions H 2 132 160 179 176 647 B 2 143 80 152 137 512 Z 0 0 0 0 0 0 Figure 4 Question #1: Write an Excel formula to determine the total points awarded to all type H network providers from all regions combined. First look at column B and decide which providers have a type H network, and then add the total points of those providers only. Column G lists the total points that each provider received. The manual step-by-step process of solving this problem involved adding values if a specific criterion was met. This can be accomplished using a SUMIF function. The first argument of the SUMIF function is the criteria_range. In this case, column B (B5: B8) contains the value to be compared to the criterion, the Network type. Chapter 5 Page 5 Chapter 5-Countif(s)/Sumif(s)/Averageif(s)/Large/Small/Rank The second argument is the criteria, in this case whether or not the network type of the provider is type H. In Excel syntax this is written as an “H”. Note that quotations marks are required as the criterion is text. The third argument is the sum_range. In this case add the values in column G in the corresponding rows 5 through 9. The resulting formula would be: =SUMIF(B5:B8,“H”, G5:G8) Since this formula is not copied, none of the cell references need to be made absolute. Question #2: Ratings below 70 for a specific provider/region are considered unacceptable. Write an Excel formula in cell H5 (not shown) to calculate the total points for BT&T earned from regions with unacceptable ratings. Write the formula so that it can be copied down the column. To do this manually, look at each of the point totals for BT&T by region. If the region has a point value of less than 70, we would include it in the sum. In this case all regions are above 70 and the total would be 0. A SUMIF adds values that meet a criterion. o The first argument is the range to compare with the criterion. In this case the range is C5:F5 which contains each region’s rating points. o The second argument is the criteria. To find values less than 70 use the syntax “<70”. Note the unusual syntax; when using a relational operator as part of the SUMIF criteria use quotation marks around the entire expression. o The third argument is the values to be added. Since this range is identical to the criteria range (C5:F5), this argument can be omitted (however, including it will work as well). The resulting formula is: =SUMIF(C5:F5,“<70”). Now this formula must be copied down the column. In cell H6, the formula should be the sum of the unacceptable ratings for Blue Phone. Copying this formula down one row to cell H6, the resulting formula will be =SUMIF(C6:F6, “<70”). The range is correctly modified so there is no need for absolute references. Since the criteria for Blue Phone is the same as the criteria for BT&T, this argument also requires no additional modifications.. Chapter 5 Page 6 Chapter 5-Countif(s)/Sumif(s)/Averageif(s)/Large/Small/Rank COMPLETING THE SUMMARY TABLE: Now return to our original example. How can the summary by network type be completed in cells B11:G13 (Figure 11)? Remember that we want to write a single Excel formula in cell C11 that will total the points for the East region for network type H and can be copied down the column and across the row to calculate the corresponding totals for types B and Z in each of the four respective regions. A 1 B C D E F G Service Ratings 2 Network Type 3 Total Possible points East Midwest South 100 100 100 West 100 Total 400 86 55 90 82 345 265 302 247 4 5 BT&T 6 Blue Phone 7 Horizen 8 Spuce H B H B 81 53 51 90 90 80 70 88 77 91 75 9 10 11 12 13 # in Total Total Total Total Total - all Summary Network East Midwest South West regions H 2 132 160 179 176 647 B 2 143 80 152 137 512 Z 0 0 0 0 0 0 Figure 5 The Solution: Again, the solution will require that values be summed together if they meet a specific criterion. The SUMIF function will be best suited to implement the solution. To implement this for only cell C11, write the Excel formula =SUMIF(B5:B8,A11,C5:C8). The criteria range contains the phone provider’s network type in cells B5:B8, the criteria “H” will be referenced as cell A11 to make copying possible later, and the sum range will encompass the East region’s data in cells C5:C8. The challenge is how to make this work when copied BOTH down the column and across the row. Let’s consider each direction separately. o What is the correct formula for cell C12 to sum the points for network type B in the East region? The formula needed will be =SUMIF(B5:B8,A12,C5:C8). Notice that the criteria_range does not change when copied down requiring absolute cell referencing for the criteria_range row references The criteria “H” in cell A11 changes to “B” (cell A12). So this row reference of the criteria argument must be relative. Neither does the sum_range change when copied down, this too will require absolute row referencing The formula at this point, before considering copying across, should be modified to =SUMIF(B$5:B$8,A12,C$5:C$8). o The formula needed in cell D11 to sum the points for network type H in the Midwest region is =SUMIF(B5:B8,A11,D5:D8). Chapter 5 Page 7 Chapter 5-Countif(s)/Sumif(s)/Averageif(s)/Large/Small/Rank Notice the criteria_range argument again stayed the same requiring absolute column references. When copying across from column C to column D the criteria argument stayed the same; this too will need an absolute column reference. And finally notice that the sum_range does change from C5:C8 to D5:D8 when copyed across from cell C11 to D11. Thus the column reference should be relative for the sum_range argument. The final formula should then be: =SUMIF($B$5:$B$8,$A11,C$5:C$8). The final formula contains a criteria range that has both an absolute column reference and absolute row reference; it never changing regardless of where it is copied. The criteria changes when copied down but remains the same when copied across, requiring an absolute column reference. The sum range, which changes when copied across but remains the same when copied down, requires an absolute row reference. In cases where formulas are copied in two directions, mixed cell referencing is often needed for a formula to result in the correct solution. Furthermore, extra $’s not only affect the readability of the formula, but can also result in incorrect formulas when the formula is copied. As a rule of thumb, only include absolute cell referencing if the formula is incorrect without it. Minimize absolute cell referencing whenever possible.

Above is a spreadsheet that you have created to keep track of all the related information including the name, salary, job level, retirement eligibility, performance review scores (1-worst to 5 best) for the past 3 years and the year of last promotion for each employee. You will be completing this worksheet by filling in the required formulas. 1. Write an Excel formula to be put in cell I3, which can be copied down the column, to calculate the average review score for the past 3 years of the employee. Round this value to the nearest hundredth. 2. Write an Excel formula in cell J3, which can be copied down the column, to determine whether this average review exceeds 4.0. The result should be a True/False Boolean value. 3. Write an Excel formula in cell F18 to determine whether (TRUE/FALSE) all the employees’ average review scores for the past 3 years exceed 4.0. Chapter 5 Page 15 Chapter 5-Countif(s)/Sumif(s)/Averageif(s)/Large/Small/Rank 4. Write an Excel formula in cell K3, which can be copied down the column, to determine whether (TRUE/FALSE) this employee is recommended for promotion this year. An employee will be recommended for promotion if they have a performance review score of over 4.0 in any of the past 3 years and have not been promoted any time after 2005. 5. Write an Excel formula in cell L3, which can be copied down the column, to determine whether (TRUE/FALSE) this employee should be placed on probation. An employee should be placed on probation if their performance review score for 2006 is lower than 2.0, or if their average performance review score is lower than 2.0. 6. Write an Excel formula in cell F19 to determine (TRUE/FALSE) if there are no employees eligible for retirement. 7. Write an Excel formula in cell K16, which can be copied across to cell L16, to calculate the total number of employees that will be recommended for promotion or probation respectively. 8. Write an Excel formula in cell F20 to calculate the total salary for all employees combined, whose job level is 6. 9. Write an Excel formula in cell F21 to determine (TRUE/FALSE) if only employees with job levels of 6 are eligible for retirement. This formula need not work if the job levels are later modified. Chapter 5 Page 16 Chapter 5-Countif(s)/Sumif(s)/Averageif(s)/Large/Small/Rank PRACTICE PROBLEM 5.5 –AIRLINE PROBLEM You and your friends are trying to choose an airline to use for your summer travel plans. If all of you use the same airline the travel agent has agreed to give you 10% discount off each ticket. Each of you has different requirements for where you wish to go and each airline flies to different locations. Some of you also have requested that the airline have a frequent flyer program. Use cell references in your formulas wherever possible. Each person’s preferences are as follows: Jane wants to fly an airline that goes to all locations. Mark wants to fly an airline that goes to NY or Chicago and has a frequent flyer program. Tom wants to fly an airline which does not go to a foreign country but does go to NY. 1. Write a formula in G2, to be copied down, to determine if Jane wants to fly Air Canada. 2. Write a formula in H2, to be copied down, to determine if Mark wants to fly Air Canada. 3. Write a formula in I2, to be copied down, to determine if Tom wants to fly Air Canada. 4. Write a formula in J2 to be copied down to determine the number of people who want to fly Air Canada. 5. Write a formula in J7 (not shown) to test if any of the airlines are acceptable to all three people. Chapter 5 Page 17
