Unlocking the Power of ANOVA: A Beginner's Guide to Hypothesis Testing
F - Distribution Continuous probability distribution: The F-distribution is a continuous probability distribution used in statistical hypothesis testing and analysis of variance (ANOVA). Fisher-Snedecor distribution: It is also known as the Fisher-Snedecor distribution, named after Ronald Fisher and George Snedecor, two prominent statisticians. Degrees of freedom: The F-distribution is defined by two parameters - the degrees of freedom for the numerator (df1) and the degrees of freedom for the denominator (df2). Positively skewed and bounded: The shape of the F-distribution is positively skewed, with its left bound at zero. The distribution's shape depends on the values of the degrees of freedom. Testing equality of variances: The F-distribution is commonly used to test hypotheses about the equality of two variances in different samples or populations. Comparing statistical models: The F-distribution is also used to compare the fit of different statistical models, particularly in the context of ANOVA. F-statistic: The F-statistic is calculated by dividing the ratio of two sample variances or mean squares from an ANOVA table. This value is then compared to critical values from the F-distribution to determine statistical significance. Applications: The F-distribution is widely used in various fields of research, including psychology, education, economics, and the natural and social sciences, for hypothesis testing and model comparison.

Non-Gaussian Probability Distribution
Continuous Non-Gaussian Probability distribution like uniform distribution, Pareto distribution, log normal distribution There are also many other non-Gaussian continuous distributions, each with their own applications and characteristics.
