relationships, or differences in a dataset by chance alone. It helps researchers draw conclusions about the population based on sample data. Statistical tests involve mathematical calculations and hypothesis testing to assess the significance of results and make inferences about the underlying population. ...

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 ...
The psychometric-structuralist approach claims to be scientific, because it uses statistical analysis to examine the test results as well as the test itself. This approach has been adopted by a great number of teachers in the West. As the current trend of linguistic theories has changed the ...
Sample size is an important component of statistical significance in that larger samples are less prone to flukes. Only randomly chosen,representative samplesshould be used in significance testing. The level at which one can accept whether an event isstatistically significantis known as the significance...
Thismultiple-comparisonpost hoc correction is used when you are performing many independent or dependent statistical tests at the same time. The problem with running many simultaneous tests is that the probability of asignificantresult increases with each test run. This post hoc test sets thesignifica...

A sample is a smaller, manageable version of a larger group. Samples are used in statistical testing when population sizes are too large.
Different types of switching models are in use, and in many cases the use of a particular model type is not justified on statistical grounds. This paper suggests a new procedure to test between different types of such models based on embedding these models within a more general one. First ...
What is the meaning of a test statistic? 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. ...
