Formula for taking an average of duplicate rows

dmg

I'm attempting to construct a formula for taking averages of multiple ratings from several raters across three vendors.

Sheet 1 looks like:

Rater - Category - Vendor A Rating - Vendor B Rating - Vendor C Rating

 

Sheet 2 looks like:

Category - Vendor A Rating Avg - Vendor B Rating Avg - Vendor C Rating Avg

 

On sheet two, I need to get the average rating for each category and vendor. The formula should look at sheet one and determine where the category matches and then average the values in that row. I believe in Excel there is a AVGIF function to do this.

 

Any help is appreciated.

It sounds like you want to use the COLLECT function:

=AVG(COLLECT([Vendor A Rating]:[Vendor A Rating], Category:Category, “Category X”))

In this example, the function takes the average of all Vendor A ratings where the category is Category X.

Hi all,

This may help in the future:

=AVERAGEIF(range, criteria, [average_range])    



Returns the average of cells that meet a given criteria.

Example: =AVERAGEIF([Value 1]200:[Value 2]280, >100)

Best,

Kara
