9 most common statistical tests used in A/B testing. Here's a breakdown:

A/B Testing is the biggest driver of conversion rate improvement (more than Customer Journey analysis, Segmentation, Surveys, and Cart Abandonment Analysis). That's why if A/B testing is NOT in your toolbox, you'd better get up to speed now. Let me help.

Here are the 9 most common statistical tests that beginners get tripped up with. And an explanation of when to use them:

1. Z-Test: Used with sample sizes, known population variance. Used to determine if there is a difference between two means. Often used for proportions like click-through rates.

2. T-Test (Student's): Smaller sample sizes, unknown population variance. Suitable for comparing means from two groups. Includes independent and paired samples t-tests.

3. Welch's T-Test: Unequal variances and/or sample sizes. An adaptation of the t-test that does not assume equal variances, offering more flexibility.

4. Chi-Squared Test: Categorical data, testing for independence or goodness of fit. Useful for assessing if there is a significant association between two categorical variables.

5. ANOVA: Comparing means of three or more groups. Ideal for understanding if there are any significant differences between the means of multiple groups.

6. Mann-Whitney U Test: Non-parametric alternative to Z-test / T-test for non-normal distributions. Comparing two independent groups, especially when the data is not normally distributed.

7. Fisher’s Exact Test: Small sample sizes, especially in 2x2 contingency tables. Used for examining the significance of the association between two kinds of classifications.

8. Regression Analysis: Relationship between a dependent variable and one/more independent variables. For more complex A/B tests to understand the impact of multiple variables on an outcome.

9. Pearson's Chi-Squared Test: Categorical data in contingency tables. Determines if there is a significant difference in the distribution of categories between groups.
