Question

Quizplus · Accepted Answer

In a completely randomized design, the total number of observations equals the sum of the number of observations in each treatment group. Therefore, the total number of observations in this design is not predetermined and can vary depending on the number of treatment groups and the number of observations in each group. The given information about the degrees of freedom does not provide any insight into the total number of observations.
