The other day, while doing consulting for one of my customers, I had a strange problem. My customer has data for several KPIs and she wants to display average of top 5 values in the dashboard.
- Now, if she wants average of all values, we can use AVERAGE() formula
- if she wants top 5 values to be highlighted, we can use LARGE() formula and CF.
but average of top 5?
I said what any consultant would say. “It is possible”
After thinking for a while, I found the solution by nesting LARGE() formula with AVERAGE() formula. Like this:
=AVERAGE(LARGE(A1:A10,{1,2,3,4,5}))
There is no need to press CTRL+SHIFT+Enter after this formula and it works fine.
You can use similar formula to get Average of bottom 5 values like this:
=AVERAGE(SMALL(A1:A10,{1,2,3,4,5}))
Now, your home work:
Ok, here is an interesting twist to this formula. My formula works fine as long as the list has at least 5 values in it. But, lets say the input range (a1:a10) is dynamic. That means, it can grow or shrink.
Now, how would you modify this formula so that it works even when there are less than 5 values ?
Go, figure that out. When you are done, come back here and post a comment.

Note: The text-formula above miss a -1. The video is correct.
😀 sorry, I made the exact same mistake as you did - initially - in the video. {0..3} is one thing, and Table.RowCount(replacements) -->3 items ={0,1,2} is another thing.
1st question : you've created a new column to put the replacements in. how ca we replace in the original column without creating a new one ?
2nd question : how can we replace the value in the entire cell and not only the text (Using ReplaceValue instead of text.Replace) ?
Thanks you in advance
Chandoo, I would be very interested to have your answers in both Yassine's questions!
Thank you for sharing,

Thank you for this! I was just doing an assignment where I was having to replace words with other words in my Excel sheet. We are starting with the basics in my class, so I know I don't have a huge list that I would need to find and replace, but this is something that could be useful down the road for me!
Hi
This is nearly perfect for my needs thank you, however I would like just the "replace" to be the result if possible please, I have tried in vain adjusting the formula without success.
Thank you in advance
Thank you! Awesome tip, and very flexible, too.
My find/replace values were in non-adjacent columns of a table containing a bunch of other data. Worked prefectly and I am now a tiny bit less clueless.
Hi!!!
I have the same question that Yassine did.
I need to replace the values in the same column. I don't want to create a new column e then have to remove the old column.
How could I could that?
That's a real fun article. It inspired me to delve deeper into the topic of List.Accumulate. I can see how the function works, but it takes an additional step to imagine how one can use it for more complex applications.
Your example also made it into my article, together with some other use-cases. Would be great to get your opinion on which other areas you would include in the article.
Let me drop the link to the page so others can too find it for further reading: https://gorilla.bi/power-query/list-accumulate/
