FUNCTIONS
AVERAGE(number1,number2,…)
COUNT(number1,number2,…)
LARGE(array,k)
MAX(number1,number2,…)
MIN(number1,number2,…)
RANK( number, ref, order)
ROUND(number, num_digits)
SMALL(array,k)
SUM(number1,number2,…)
The INPUT data for this
problem is given in cells
A4:E22 and M4:M22.
10.
(4 pts) Write an Excel formula in cell A23 to determine the number of players on the J-Excel franchise baseball
team.
11.
(3 pts) Write an Excel formula in cell C23, which can be copied across to cell E23, to determine the total
number of hits for the J-Excel franchise baseball team. NOTE: Remember that the wording of this problem
refers to determining the total number of hits initially, but then determining the total RBIs (runs batted in) and
the total number of home runs, respectively, as the formula is copied.
12.
(5 pts) When I was setting up the worksheet, I was debating whether to leave the cells blank instead of put in a
zero for players’ hits, runs batted in and home runs in the range C4:E22.
a.
Will changing the zeroes to blanks change the results in cells C23:E23? Yes or No.
b.
What if I want to find the AVERAGE number of hits for the team? Will it return the same
results with blank values as having zero values? Yes or No. Explain.
13.
(5 pts) Write an Excel formula in cell F4, which can be copied down and across to cell H22, to determine the
batting average for John. FYI: the batting average is determined by the number of hits per at bat.
14.
(6 pts) Write an Excel formula in cell I4, which can be copied down and across to cell K22, to determine john’s
batting average ranking in relation to the rest of the team’s batting average where a rank 1 designates the person
with the best/highest batting average.
15.
(6 pts) Write an Excel formula in cell L4, which can be copied down to cell L22, to determine the average for
john’s batting average, RBI and home run rank values rounded to the nearest whole number.
16.
(4 pts) In cells M4:M22, I averaged the ranked values (in columns I, J, and K) without using a function to round
the resulting value. In N4, I put the formula =L4-M4 and copied it down to N22. Be sure to explain:
 Why are some of the values zero?
 Why are some of the values positive?
 Why are some of the values negative?
17.
(6 pts) Write an Excel formula in cell Q4, which can be copied down and across to cell S6, to determine the top
batting average value on the team.

ANSWER
=COUNT(B4:B22)
Can also use columns C, D, and E
No $ allowed
=SUM(C4:C22)
Optional $ on row
A. No
B. No it will not return the same results. That is, the average will be
different if using blank values instead of zeroes. Since blank values
are ignored, the sum of the values would be the same (per above),
but the number of values to divide it by to make the average would
be different i.e. it would count the number of values differently
since blanks would be ignored but zeroes would be counted.
=C4/$B4
No extra $ allowed
=RANK(F4,F$4:F$22,0)
No extra $ allowed
Optional 3rd argument i.e. can be left out since is the default value
=ROUND(AVERAGE(I4:K4),0)
Optional $ on column
The precision for column L changed due to the round function so there is
no decimal portion; whereas the values in column N are formatted to a
whole value so the precise value could either be actually less than the
formatted value, more than the formatted value, or the same, thus giving
positive, negative, and zero values in column N respectively.
=LARGE(F$4:F$22,$P4)
No extra $ allowed
SCORE _____________/50
