Compare r to the appropriate critical value in the table. WebMar 26, 2024 · A standardized test statistic for a hypothesis test is the statistic that is formed by subtracting from the statistic of interest its mean and dividing by its standard deviation. For example, reviewing Example 8.1. 3, if instead of working with the sample mean X ¯ we instead work with the test statistic.
