The MEAN function computes the mean of a numeric vector. MEAN calls the IDL function MOMENT.

Set this keyword to cause the routine to check for occurrences of the IEEE floating-point value NaN in the input data. Elements with the value NaN are treated as missing data. (See Special Floating-Point Values for more information on IEEE floating-point values.)

x = [65, 63, 67, 64, 68, 62, 70, 66, 68, 67, 69, 71, 66, 65, 70]

*;
Define the n-element vector of sample data.*

result = MEAN(x)*;
Compute the standard deviation.*
