How do you know if your process is following a normal distribution? Use these tests to find out.
Normal Distribution (AKA Gaussian Probability Distribution)
The Normal distribution is used to analyze data when there is an equally likely chance of being above or below the mean for continuous data whose histogram fits a bell curve.
The T distribution and T tests are used to determine the likelihood of various conditions occurring for small sample sizes (<=30).
A Paired T Distribution, Paired T Test, Paired Comparison test, Paired Sample Test compares the mean & standard deviation of two groups
The F-distribution, also known Fisher-Snedecor distribution is extensively used to test for equality of variances from two normal populations
