What are Statistical Tests? Statistical tests are a way of mathematically determining whether two sets of data are significantly different from each other. To do this, statistical tests use several statistical measures, such as the mean, standard deviation, and coefficient of vari...
Problems arise in tests of statistical significance because researchers are usually working withsamplesof larger populations and not the populations themselves. As a result, the samples must be representative of the population, so the data contained in the sample must not be biased in any way. In ...

Statistical tests make some common assumptions about the data they are testing:Independence of observations (a.k.a. no autocorrelation): The observations/variables you include in your test are not related (for example, multiple measurements of a single test subject are not independent, while ...
A test statistic is a numerical quantity used to measure the discrepancy between sample data and assumed properties of the population involved. Test statistics are used in hypothesis testing, a method for evaluating statistical evidence. What is a test statistic example?
