What would be the most appropriate equation to calculate the model degrees of freedom (df_M)? A) df_M = k - 1 B) df_M = k + 1 C) df_M = k × 1 D) df_M = k / 1

Question

Quizplus · Accepted Answer

The appropriate equation to calculate the model degrees of freedom is df_M = k - 1, where k represents the number of groups or factors. This equation is commonly used in ANOVA (analysis of variance) to determine the degrees of freedom for the overall model. By subtracting 1 from the number of groups, we take into account the fixed effects of the model, which reduces the overall degrees of freedom. Therefore, choice A is the correct answer.
