Most statistical tests assume that the variables being analyzed are normally distributed in the population. This assumption is necessary for accurate and reliable results from the statistical tests. Normal distribution implies that the majority of the observations are clustered around the central value, and symmetrical in distribution. Therefore, any statistical analysis that relies on the assumption of normal distribution requires that the variables follow a bell-shaped curve.
