Excel Pivot - 计算平均值 > XX

Question

Data table simplified - read only:

 <table border=1> <tr><th>Date</th><th>Hours</th></tr> <tr><td>Jan. 1</td><td>6.5</td></tr> <tr><td>Jan. 2</td><td>8.5</td></tr> <tr><td>Jan. 3</td><td>7.5</td></tr> <tr><td>Jan. 4</td><td>9.0</td></tr> </table>

Now I would like a pivot table that can calculate the average number of hours - only taking into account the days where the number of hours are > 8.0. Ie. for the above data the pivot should return 8.75.

I've tried with calculated field: =If(Hours > 8, Hours, NULL) - or blanks instead of null or similar.

Please help.

Answer 1

You don't need a Pivot table. Just use =AverageIf([Range of Hours],">8")

Edit:

To achieve through Pivot Table, I can only think of using "measure". But it could be quite slow for 120k rows as the Filter() function need to go through each row one by one.

1. create a the Pivot Table with the checkbox "Add this data to the Data Model" clicked;
2. Right-click on the "Range" (or the table name if your data is a table) in the Field List and choose "Add Measure"
3. Enter the measure's info and use =SUMX(Range, if(Range[Hour]>8, Range[Hour],0))/ COUNTROWS(FILTER(ALL(Range), Range[Hour]>8)) as formula (replace "Range" with Table name if source data is a table). And click "OK".

Then, you can use this measure to get the average value you want.
