The number of scores free to vary when estimating a population parameter is/are:
A)degrees of freedom
B)number of scores minus 1
C)number of scores multiplied by the standard deviation
D)both A and B

Question

Quizplus · Accepted Answer

The number of scores free to vary when estimating a population parameter is known as the degrees of freedom (A). The calculation for degrees of freedom typically involves subtracting 1 from the sample size (B), so both A and B are correct. However, C is not correct as it involves multiplying the number of scores by the standard deviation, which is not related to degrees of freedom.
