Read Before you use: Here you will find some lists that will redirect to open statistical analysis tools. We have searched some tools and provided you here. You can also comment to allow us more tools to add to this list. We strictly advise you to cite the calculators you use and present in your future research. (Clink on the respective names to redirect to your calculator)

1. Mann- Whitney U Test Calculator - The Mann-Whitney U test is a nonparametric test that allows two groups or conditions or treatments to be compared without making the assumption that values are normally distributed.

2. Binomial Test Calculator - This binomial test calculator determines the probability of a particular outcome (K) across a certain number of trials (n), where there are precisely two possible outcomes.

3. One-Way Anova - The one-way, or one-factor, ANOVA test for independent measures is designed to compare the means of three or more independent samples (treatments) simultaneously.

4. Chi-Square Test Calculators - (Calculator 1) and (Calculator 2)

5. Fisher Exact Test Calculator -

6. Chi-Square Calculator for Goodness of Fit -

7. Student T-Test Calculator for Comparing 2 Independent Means - This test is used when you're looking at a numerical variable - for example, height - and then comparing the averages of two separate populations or groups (e.g., males and females).

8. T-Test Calculator for 2 Dependent Means - The t-test for dependent means (also called a repeated-measures t-test, paired samples t-test, matched pairs t-test and matched samples t-test) is used to compare the means of two sets of scores that are directly related to each other.

9. Single Sample T-Test Calculator - A single sample t-test (or one sample t-test) is used to compare the mean of a single sample of scores to a known or hypothetical population mean.

10. Mann-Whitney U Test Calculator - The Mann-Whitney U test is a nonparametric test that allows two groups or conditions or treatments to be compared without making the assumption that values are normally distributed.

11. Wilcoxon Signed-Rank Test Calculator - The Wilcoxon test is a nonparametric test designed to evaluate the difference between two treatments or conditions where the samples are correlated. In particular, it is suitable for evaluating the data from a repeated-measures design in a situation where the prerequisites for a dependent samples t-test are not met.
