Formula to average last 25 entries in a column?
Guess I have a duel question.
First, I have numerous columns of data, all numerical. New entries are entered at the end of the column. Is there a formula to average just the last 25 entries in the column? (Bottom of column up) Second question pertains to the ability to "auto populate". I have a column of names. (three dozen). I would then like to auto populate the single column of names, matching the names with the average data obtained from the above. (average of last 25, 50, 100,etc entries) Data changes daily? Any help would be greatly appreciated. |

Formula to average last 25 entries in a column?
Hi,
Average last 25 entries =AVERAGE(OFFSET(A1,COUNTA(A:A)-25,):OFFSET(A1,COUNTA(A:A),)) I don't understand the second question -- Mike When competing hypotheses are otherwise equal, adopt the hypothesis that introduces the fewest assumptions while still sufficiently answering the question.

Sorry Mike, I know what I want, just don't know how to say it.
Maybe an example will help. Data Sheet one Data Sheet two Column 1 Column 1 Column 2 Column 3 Column 4 Ralph Sam 199 496 408 Sam Ralph 210 333 535 John Mike 75 322 647 Mike Tim 498 354 657 Tim John 637 577 353 Looking to take the information from Data Sheet two, and auto populate that data into the matching name on data sheet one. I know I can drag the information from one to the other, but there are numerous entries for each. Better?

1st formula should perhaps have been better shown as:
=AVERAGE(OFFSET(B$1,MAX(COUNT(B:B)-25,0),,25)) So it can be copied along to other columns.
