Critical range statistics
WebT and P are inextricably linked. They go arm in arm, like Tweedledee and Tweedledum. Here's why. When you perform a t-test, you're usually trying to find evidence of a significant difference between population means (2-sample t) or between the population mean and a hypothesized value (1-sample t). The t-value measures the size of the difference ... WebThe third and last step is to compare each of the \(k(k-1)/2\) test statistics against its corresponding critical \(r_{ij}\) value. Those pairs that have a test statistic that exceeds the critical value are significant at the \(\alpha\) level. Example: Sample proportions: To illustrate the Marascuillo procedure, we use the data from the ...
