Statistics Formulas. This web page lists statistics formulas used in the Stat Trek tutorials. Each formula links to a web page that explains how to use the formula. Population mean = μ = ( Σ Xi ) / N. Population standard deviation = σ = sqrt [ Σ ( Xi - μ )2 / N ] Population variance = σ2 = Σ ( Xi - μ )2 / N.

Similarly, statistics play a crucial role in the analysis of data in epidemiology. Data analysis helps in the determination of factors influencing diseases in a target population. It also aids researchers to identify distribution patterns and make use of the information to control health problems in society.

Probability is the measure of the likelihood that an event will occur. See glossary of probability and statistics. Probability is quantified as a number between 0 and 1, where, loosely speaking, 0 indicates impossibility and 1 indicates certainty. The higher the probability of an event, the more likely it is that the event will occur.
