Stephen23 on 19 Jan Jorge Guerra : you should never use the variable how do you find the mean and the variance sumbecause this will shadow cind inbuilt sum function so it will not work. For the same reason never use variable names celllengthsizeijtableetc. Beginners make the mistake of re-assigning name of important functions, and are then surprised when the inbuilt function does not work.

Mean is the average -- the sum divided by the number of entries.

Variance is the sum of the squares of the values minus the meanthen take the square root and divided by the number of vzriance. You can vectorize the calculation using sum. To use a for loop to calculate sums, initialize a running total to 0, and then each iteration of the loop, add the current value to the running total. Thank you Walter Roberson for the answer. That helped me a lot.

Jurgen on 19 Dec Oh and wikipedia disagrees. A very important assumption. John D'Errico on 24 Jul Jurgen - you make no sense in some of what you said, although you are correct about the square root being incorrect in this answer. Variance has no square root in it. A variance is something you can compute from the data, or for a population, but there is no assumption about the underlying distribution, nor is there any need to make what is meant by commutative in math an assumption.
