When the sample size is 15 and you are doing a t test, the number of degrees of freedom is 15.
true or false
False.
When the sample size is 15 and you are doing a t-test, the number of degrees of freedom is actually 14.
The degrees of freedom for a t-test is calculated by subtracting 1 from the sample size. Therefore, in this case, the degrees of freedom would be 15 - 1 = 14.
