What is the calculated value in a statistical test?

• A. The number the researcher is left with after the statistical test has been calculated.
• B. The critical value from the critical values table.
• C. The significance level chosen for the test.
• D. The sample size (N) of the study.

Answer: (A)

The calculated value is the result you obtain after applying the test’s formula to your data. It’s the actual statistic produced by the calculation (for example a t-value, z-score, F statistic, or chi-square value), which then serves as the basis for deciding whether the observed effect is significant. The other terms are about thresholds or inputs: the critical value is the cutoff from the distribution used to judge significance, the significance level is the chosen alpha, and the sample size is how many observations you collected. So the number left after performing the calculation—the test statistic—describes the outcome of the test itself.
