pass fail
Hi how would I set up a column to give the average of pass to fail rate?
i.e. if A1 50 then put pass in C3 else put fail then give the average of passes to fails in cell C20 if there were 19 rows? Thanks Tricia |

Thanks Tricia Hi in cells C1:C125 I have =IF(A150,"pass","fail") to =IF(A12550,"pass","fail") how do I get an average of the cells C1:C125 Thanks Tricia |
Hi Tricia
(is this homework? - sounds like the sort of problem i set as a revision exercise) however, i'm not exactly sure what an an average of passes to fails is but i'm guessing that the COUNTIF function is the way to go. - if this is homework stop reading now and go try it :) number of passes =COUNTIF(C1:C19,"pass") number of fails =COUNTIF(C1:C19,"fail") Cheers JulieD "Tricia" wrote in message ...

what do you mean "average of passes to fails"?
There will be a single discrete number of passes, and a single discrete number of failures. What is there to average? If you mean the *ratio* of passes to fails, assuming C1: =IF(A150,"pass","fail"), or C1: =IF(A1="","",IF(A150,"pass","fail")) Then C20: =COUNTIF(C1:C19,"pass")/COUNTIF(C1:C19,"fail") or if you mean the ratio of passes to total attempts: C20: =COUNTIF(C1:C19,"pass")/SUM(COUNTIF(C1:C19,{"pass","fail"})) In article , "Tricia" wrote: Hi how would I set up a column to give the average of pass to fail rate? i.e. if A1 50 then put pass in C3 else put fail then give the average of passes to fails in cell C20 if there were 19 rows? |
