M mean A returns the mean of the elements of A along the first array dimension whose size does not equal 1. E3x is e 3 x and e 3x is e 3 x. If you want to calculate the average of only the values that meet certain criteria use the AVERAGEIF function or the AVERAGEIFS function.

If you want to include logical values and text representations of numbers in a reference as part of the calculation use the AVERAGEA function. If we take the limit as n approaches infinity then we will get the average value. What I want to do in this video is think about the idea of an average value of a function over some closed interval so what do I mean by that and how could we think about what average value of a function even means so lets say thats my y-axis and lets say that this is my this right over here is my x-axis and let me draw a function here so lets say the function looks something like that. If A is a vector then mean A returns the mean of the elements.
