How does Smartsheet calculate TRIMMEAD (Excel)?

Calculating the mean (AVG) taken by excluding a percentage of data points from the top and bottom tails of a data set.

Thank you so much.

    Hi @Jeff Morin ,

    Smartsheets doesn't have an equivalent function. You could replicate the function with a formula. Adjust the 0.2 and 0.8 to percent of data you want removed from the average, and try:

    =AVG(COLLECT( range:range, AND(RANKEQ(@cell, range:range)>ROUND(COUNT(rang:range)*0.2), RANKEQ(@cell, range:range)<ROUND(COUNT(range:range)*0.8))))



    I'm grateful for your "Vote Up" or "Insightful". Thank you for contributing to the Community.

  • Hi Mark! -

    Thanks for the above- I tried using the formula but I am getting an "INCORRECT ARGUMENT SET" error.

    I noticed the missing "e" in rage:range for the 0.2 calculation but I can't seem to figure out what else I am missing!

    Thanks for your help!
