Finding the average of the first 75 points of array

[eo489]

Basically I have an array with 7500 values.  I want to take the first 75 values and find the average of those.  I'm struggling with getting the first 75, I tried for loop with an N value of 75 and it still gave me all 7500 values in an array, maybe because of indexing? Help would be much appreciated

Hi eo,

when you need a subset of your array then you should use ArraySubset...
