In order to compute the test statistic or t value, you must first approximate the sample size through calculating which of the following?
A) Pooled variance
B) Standard deviation
C) Degrees of freedom
D) Mean score

Question

Quizplus · Accepted Answer

The degree of freedom is used to approximate the sample size, as it determines the number of independent observations in the data set. The t value or test statistic is calculated using the sample mean, population mean, standard deviation, and degree of freedom. Therefore, option C (Degrees of freedom) is the best choice for approximating the sample size.
