Statistical tests are used in hypothesis testing. They can be used to:determine whether a predictor variable has a statistically significant relationship with an outcome variable. estimate the difference between two or more groups.Statistical tests assume a null hypothesis of no relationship or no ...
2. Goodness-Of-Fit In statistical hypothesis testing, the Chi-Square Goodness-of-Fit test determines whether a variable is likely to come from a given distribution. We must have a set of data values and an idea of the distribution of this data. We can use this test when we have value ...
While test statistics are a crucial part of hypothesis testing, you’ll probably let your statistical software calculate the p-value for the test. However, understanding test statistics will boost your comprehension of what a hypothesis test actually assesses. ...
Mauchly’s test for sphericity can be run in the majority of statistical software, where it tends to be the default test for sphericity. Mauchly’s test is ideal for mid-size samples. It may fail to detect sphericity in small samples and it may over-detect in large samples. ...
