What is a one-way analysis of variance (ANOVA) used for? Explain why post-hoc tests are referred to as unplanned comparisons. In what instances would you use a post-hoc test? In what instances would you not use a post-hoc test?
The Tukey test is a post hoc test in that the comparisons between variables are made after the data has already been collected. This differs from an a priori test, in which these comparisons are made in advance. In the former case, you might look at the mile run times of students in t...
Here are some of the most common types of post hoc test. Tukey’s Honestly Significant Difference (HSD) This test compares all possible pairs of means and controls for the familywise error rate. It is most appropriate when all groups have equal sample sizes. Bonferroni This is a very conser...

This can be done to test if the system can handle expected usage in general, or to test how a specific functionality would cope, like the “add to basket” example we mentioned above. This is sometimes called “unit testing”. 2. Stress testing Stress testing is another form of...
A similar Dunnett’s post hoc test, comparing the pre-pandemic and post-pandemic periods reveals that the difference is statistically significant with respect to cognitive [mean difference = − 0.22,p = 0.012], affective [mean difference = − 0.92,p < 0.001] and soci...
A/B testing (also called split testing) is comparing two versions of a web page to figure out the better performing variation. Learn more with examples.
A sequence or collection of test cases is called a test suite. A test case document includes test steps, test data, preconditions and the postconditions that verify requirements. Why test cases are important Test cases define what must be done to test a system, including the steps executed ...
Test #1 Notice that once all 25concurrent usersare logged in and doing work, the throughput stays fairly consistent. This is expected. Test #2 Now notice what throughput looks like on a test that did not perform as well as in the last example. ...
