Random variable is usually denoted by X. A random variable may be discrete or 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..
