The term is best known as a mechanical effect, and is used as an analogy to a falling row of dominoes. It typically refers to a linked sequence of events where the time between successive events is relatively small.
9 terms. What is the difference between a z test and a t-test. Z: tests probability sample was drawn from a population with a known mean and known standard deviation. T; tests probability sample was drawn from a population with known mean but unknown standard deviation. z-test.
There are four major types of significance tests. The Z-test and t-test look at differences in the mean values and the chi-squared and F-tests look at differences in variances. With experimental designs, we use the tests of significance for samples, the t-test and the F-test, not the tests for populations.
