Amongst which of the following is not a descriptive statistic?
t-test
mean
standard deviation
range
Correct Answer :
A. t-test
Inferential statistics such as the t-test are used to assess whether or not there is a statistically significant difference between the means of two groups that are connected in some characteristics. In order to evaluate statistical significance, a t-test takes into consideration the t-statistic, the t-distribution values, and the degrees of freedom. An analysis of variance must be used in order to run a test with three or more mean values.
