WebbIn statistics, the mean is the most common method to measure the center of a data set. It’s a fundamental yet important part of the statistical analysis of data. If we calculate the average value of the population set, then it is called the population mean. WebbResult. A quick check after mean centering is comparing some descriptive statistics for the original and centered variables: the centered variable must have an exactly zero mean;; the centered and original variables must have the exact same standard deviations.; If these 2 checks hold, we can be pretty confident our mean centering was done properly.
