DATAtab's goal is to make the world of statistical data analysis as simple as possible, no installation and easy to use. Of course, we would also be pleased if you take a look at our second project Statisty.
Here you can find out everything about location parameters and dispersion parameters and how you can describe and clearly present your data using characteristic values.
Here you will find everything about hypothesis testing: One sample t-test, Unpaired t-test, Paired t-test and Chi-square test. You will also find tutorials for non-parametric statistical procedures such as the Mann-Whitney u-Test and Wilcoxon-Test. mann-whitney-u-test and the Wilcoxon test
The regression provides information about the influence of one or more independent variables on the dependent variable. Here are simple explanations of linear regression and logistic regression.
Correlation analyses allow you to analyze the linear association between variables. Learn when to use Pearson correlation or Spearman rank correlation. With partial correlation, you can calculate the correlation between two variables to the exclusion of a third variable.
The partial correlation shows you the correlation between two variables to the exclusion of a third variable.
The Levene Test checks your data for variance equality. Thus, the levene test is used as a prerequisite test for many hypothesis tests.
The p-value is needed for every hypothesis test to be able to make a statement whether the null hypothesis is accepted or rejected.
DATAtab provides you with tables with distributions and helpful explanations of the distribution functions. These include the Table of t-distribution and the Table of chi-squared distribution
With a contingency table you can get an overview of two categorical variables in the statistics.
In an equivalence trial, the statistical test aims at showing that two treatments are not too different in characteristics and a non-inferiority trial wants to show that an experimental treatment is not worse than an established treatment.
If there is a clear cause-effect relationship between two variables, then we can speak of causality. Learn more about causality in our tutorial.
Multicollinearity is when two or more independent variables have a high correlation.
Learn how to calculate the effect size for the t-test for independent samples.
