test statistic
A value calculated from sample data during a hypothesis test, used to decide whether to reject the null hypothesis. Technical term in statistics.
In a t-test, the t-value is calculated as the test statistic.
If the test statistic falls into the rejection region, we reject the null hypothesis.
Compound of 検定 (test, verification) and 統計量 (statistic). A straightforward technical term formed from standard Sino-Japanese elements.
