Entering Equations in Excel
Homework
I.
Make an Excel spreadsheet for your lab grades in this course
A. Open Excel and enter your name in a cell. Format the cell Bold.
B. In the cell below this one, enter “Assignment” (do not enter the quotes – the
quotes here and below are only to mark what you enter).
C. In a column underneath the cell with Assignment, enter “Lab 1”, “Lab 2”, …,
“Lab 5”, each one in the cell underneath the one before.
D. In the cell to the right of Assignment, enter “Grade”
E. If necessary, make the column with Assignment wider to show the whole word.
F. In the cells opposite each lab, enter your grade for that lab. Leave cells blank if
you did not turn that lab in.
G. Below the last cell in the Assignment column, enter “Average for labs turned
in”
H. Below that cell, enter “Sum of lab grades”
I. Below that cell, enter “Average for all labs”
J. Format the cells in G, H and I as Right Aligned so that the whole label shows.
K. In the cell underneath your actual grades, opposite Average for labs turned in,
enter the formula for the average of all five labs {=average([then drag over all
spaces for lab grades])}. Excel will ignore any blank cells in calculating the
average.
L. In the cell underneath that, opposite Sum of all lab grades, enter the formula for
the sum of all of your lab grades, listing each cell individually, separated by +
signs (example: =C3+C4+C5+C6+C7, but use the cell numbers for your
spreadsheet)
M. In the cell underneath that, opposite Average for all labs, enter the formula for
the sum in the cell above divided by 5, the number of labs due (example: =C9/5,
but use the cell numbers for your spreadsheet). This formula counts missing labs
as zeroes, the way they will count in the final course grade.
N. Save your spreadsheet.
O. Click on the cell with the formula you entered in step L, Sum of all lab grades.
Make sure the formula is showing in the formula bar.
II. Show me that you have done this by:
A. Tap the <Print Screen> key (top-most row, on the right). This places a copy of
the screen on the clipboard.
B. Open Microsoft Word and use File > Page Setup > Paper Size to change
Orientation from Portrait to Landscape
C. Paste the clipboard into your document
D. Print this page out and turn it in as part of the homework assignment.
