Now consider the following spreadsheet:
Formula in cell D2 is = (B2/C2)
Replicating this formula (by highlighting then drag down to D7) gives all the formulas needed in cells D3 to D7
Formula in D8 (to find average) can be done in 3 ways:
= AVERAGE (C2:C7) or
= SUM (C2:C7)/6 or
= (C2+C3+C4+C5+C6+C7)/6
Formula in D9 to find out maximum value in column is = MAX (C2:C7)
- Problems associated with spreadsheets:
