**Question:**

The easiest way to explain what I'm trying to do is to give an example of the data, so here's a simple example:

A B C D

Name1 4 Name4 3

Name2 3 Name4 2

Name3 5 Name1 1.4

Name4 3 Name3 6

Name5 1 Name6 8

Name2 3 Name7 10

Name1 4 Name5 2

With that above data, I want to produce a pair of columns, the first that has a list of all the unique entries in A and C, the second having the average of the corresponding values in either B or D for the entry in A or C. The result should look something like:

Name1 3.133333

Name2 3

etc.

Columns A and C are guaranteed to be strings, B and D are guaranteed to be positive numbers. It is also guaranteed that A and C will never contain the same value.

Then I also want to do another query similar, except instead of taking the average of all the corresponding values, I want to count the number of times some specific value occurs with respect to the total. As an example:

A B C D E

Name1 4 Name4 3 Y

Name2 3 Name4 2 Y

Name3 5 Name1 1.4 N

Name4 3 Name3 6 Y

Name5 1 Name6 8 Y

Name2 3 Name7 10 N

Name1 4 Name5 2 Y

In this case, I want to count the percentage of times Y occurs in E over the total number of times each item in A and C occurs. This time, B and D are no longer important. For example, Name1 occurs 3 times, and has an E value of Y twice, so I want 0.66667. So the result should look like:

Name1 0.66667

Name2 0.5

Name3 0.5

Name4 1

If at any point any of this isn't clear, please ask so I can clarify. Thanks.

**Solution:**

Screenshot of Spreadsheet:

I have the following formula in cell G1:

=query({A:B;C:D},"Select Col1,avg(Col2) where Col1<>'' group by Col1 label Col1 'Name', avg(Col2) 'Average' format avg(Col2) '0.00'")

and the following formula in cell J1:

=query(arrayformula(iferror(query({{A:A,E:E,E:E};{C:C,E:E,E:E}},"select Col1,count(Col3) where Col1<>'' group by Col1 pivot Col2")*1,query({{A:A,E:E,E:E};{C:C,E:E,E:E}},"select Col1,count(Col3) where Col1<>'' group by Col1 pivot Col2"))),"select Col1,(Col3/(Col2+Col3)) label Col1 'Name', (Col3/(Col2+Col3)) 'Percentage' format (Col3/(Col2+Col3)) '0.00'")
