PQ - need to get average of multiple columns but some of the columns are blank

[Anonymous]

I have a csv file from a customer survey with 3 survey questions and I would like to get an overall survey score.  My formula is basically (column 1 + column 2+column 3)/3.  This works perfectly except when one of the survey questions was not answered.  When that happens, my score is also blank

What I need is to really only look at the columns that have data.  If only one survey question was answered, then have that single score be divided by 1.  If only 2 questions where answered, then sum those 2 and divide by 2 etc

Thoughts?

As you can see below, the 2nd and 3rd question was skipped so it's causing the Survey Score to be blank

Use below formula for average to handle nulls

= List.Average({[Agent Experience],[First Call Resolution],[Overall Satisfaction]})
