"Understanding Kurtosis and How to Determine if Your Data has a Normal Distribution."
What is Kurtosis? Kurtosis is a statistical term that measures the degree of peaked Ness or flatness of a distribution compared to the normal distribution. A distribution with high kurtosis has a sharp peak and fat tails, indicating that it has a higher probability of extreme values than a normal distribution. On the other hand, a distribution with low kurtosis has a flatter peak and thinner tails, indicating that it has a lower probability of extreme values than a normal distribution.

"Unlocking the Power of Chi Square: A Guide to Statistical Analysis"
Chi Square Distribution The Chi-Square distribution, also written as χ² distribution, is a continuous probability distribution that is widely used in statistical hypothesis testing, particularly in the context of goodness-of-fit tests and tests for independence in contingency tables. It arises when the sum of the squares of independent standard normal random variables follows this distribution.

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.
