Thread: search a column for starting value and average the data corronsponding

Help

Im trying to average the data - like in the attached workbook. I cant figure out how to build a formula to do this automatically, by averaging the data which contains the first 4 values like in column E and matching this to column A and averaging all the data in column B coresponding to Column A correct match.

Does this make sense?

Of course you are not using dates so change the formula accordingly

=sumproduct(isnumber(search(e2,$a$2:$a$18,1))*($b$2:$b$18))/sumproduct(--isnumber(search(e2,$a$2:$a$18,1)))
