How do I calculate a Group Average for the Most Recent Date?

Scott Anderson

I have assessment scores for individuals within different groups (Male or Female). The assessments are taken over time as a sort of "pulse check." Now, I want to be able show a group average (average for all Males and average for all Females) for the most recent round of assessments. How do I calculate that?

I've tried combinations of Max, Ave, and Collect statements, but can't seem to get them to work in the right order. The picture below shows what I'm trying to accomplish.

Any guidance? Thanks in advance.

Hi Scott,

You're on the right track with MAX(COLLECT and AVG(COLLECT. First we can use a formula to return the most recent date, with the MAX(COLLECT formula, that looks at the Date Range, then matches the Gender with the gender listed in your GenderAvg column (I've named it this because you can't have two column with the same name)

=MAX(COLLECT(Date:Date, Gender:Gender, =GenderAvg@row))

Then, once you have the dates, you can use this in your next formula, the AVG(COLLECT formula. An AVG(COLLECT works like this:

=AVG(COLLECT([Range to Avg]:[Range to Avg], [Criteria Range 1]:[Criteria Range 1], Criteria 1, [Criteria Range 2]:[Criteria Range 2], Criteria 2...) etc

So in your sheet, try the following:

=AVG(COLLECT(Score:Score, Date:Date, =[Most Recent]@row, Gender:Gender, =GenderAvg@row))

Here are some Help Center articles I used: MAX function / AVG function / Collect function / @row function

Let me know if this works for you, or if you have any other questions!

Cheers,

Genevieve

Genevieve, Thank you! I've been trying for a few days to get this to work. What I was missing was that piece of referencing the average formula back to the Max Date and the Gender column. It all works now!!! Thank you!

Wonderful! I'm so glad to hear it works. :)
