Detailed explanation-1: -Key Differences Between Sample Mean and Population Mean The arithmetic mean of the entire population is called population mean. The sample is represented by x̄ (pronounced as an x bar). On the other hand, population mean is labelled as (Greek term mu).
Detailed explanation-2: - = ( Xi ) / N. The symbol ‘’ represents the population mean. The symbol ‘ Xi’ represents the sum of all scores present in the population (say, in this case) X1 X2 X3 and so on. The symbol ‘N’ represents the total number of individuals or cases in the population.
Detailed explanation-3: -Mu-X-bar is equal to Mu. Mu stands for the population mean, and Mu-X-bar stands for the mean of the sampling distribution of all the sample mean. The standard deviation of the sampling distribution is symbolized by Sigma-X-bar and is equal to Sigma divided by the square root of n.
