T and Z tests are parametric tests that are designed to measure the differences in behavior between a sample population and a universal population. How is the T/Z calculation represented on a bell curve? Is it a standard deviation or variance?© BrainMass Inc. brainmass.com June 4, 2020, 12:08 am ad1c9bdddf
The t and z calculations are very similar, with the only difference in the calculations being that t uses the sample standard deviation while z uses the population standard deviation.
When t is calculated for small sample ...
The expert determines how T/Z calculations are represented on a bell curve. Whether it is a standard deviation or a variance is determined.
