Both the Mean.vi function mentioned by Roberto and the Add Array Elements method suggested by Gorka works just fine for calculationg the average of numbers in an array if your data consists of real numbers. However, if you are dealing with complex numbers you should consider the latter method since the Mean.vi function is not compatible with complex numbers. In other words, if you wire an array of complex numbers to Mean.vi you get the mean value for the real parts only. However, the same array wired to an Add Array Elements followed by a division of the array dimension, as suggested by Gorka, will result in the complex mean value. /Mikael
