The approach of this Handbook is to present commonly used steps and formulas in statistics, provide an example of how to conduct the calculations by hand, and then an example of software output.
Statistical formulas can be defined as the group of statistical symbols used to make a statistical statement. Here we will discuss popular formulas and what they stand for. Population Mean. The term population mean, which is the parameter of a given population, is represented by: ? = ( ? Xi ) / N. The symbol ‘?’ represents the population mean.
