The mean is the numerical average of the data set, and we use the mean to describe the data set with a single value that represents the center of the data. Many statistical analyses use the mean as a standard measure of the center of the distribution of the data..

Introduction. Population mean . gives no idea about the phenotypic values recorded on different individuals whether values are same or different.. If values are same or similar, then population mean also will be the same. If values are different from individual to individual then population mean cannot tell about the distribution of values around the central value, the population mean.. ANOVA is comparison of means.
