Calculation of a running mean
I use a spreadsheet to record test scores. There are 12 tests to be taken
over the year and I would like to calculate a running mean of the scores as they are inputted. I have tried just calculating a mean but the spreadsheet does not appear to be able to cope with calculating a mean from a formula which refers to empty cells (those cells referring to the tests which have yet to be taken).I am using Excel 2003 and I don't have the statistics package available. How do I calculate a running mean? |

Calculation of a running mean
If data is in cells A1:A12, then =AVERAGE(A1:A12) will calculate average if
future test scores are left blank. Adding new data will update average. "clatters69" wrote: I use a spreadsheet to record test scores.
