Question

Which of the following would cause Fobt to increase?

a. an increase in the difference between the means
b. an increase in the the within-groups variability
c. an increase in the magnitude of the independent variable's effect
d. a and b
e. a and c

Answer 1

The Fobt (F-Test) will increase if there is an increase in the difference between the means or an increase in the magnitude of the independent variable's effect.

Step-by-step explanation:

The correct answer is e. a and c. An increase in the difference between the means (a) and an increase in the magnitude of the independent variable's effect (c) would cause the Fobt (F-Test) to increase. When there is a larger difference between the means, it indicates a stronger effect of the independent variable. This results in a larger Fobt value, which measures the ratio of between-group variability to within-group variability.
