Okay so here’s what I remember from 4th grade (salt it heavily; that was decades ago and I had to flake on statistics class):

There are 3 kinds of ‘average’: The mean: values of all the things added together, divided by number of things

Median: take the… I think the mean, but maybe highest and lowest, then find the actual number in the data set closest to it

Mode: number that occurs most often in the data set.

Pretty sure this uses mean. That’s the common one. Look what happens to that data when you remove extreme outliers, or just the top 1%.
