Question 111 Skipped Experiment is conducted with two factors at three levels each. The degrees of freedom for interaction will be Correct answer 4 2 6

The correct answer is **4**.Here's why:* **Degrees of freedom for Factor A:** (Number of levels of A - 1) = (3 - 1) = 2* **Degrees of freedom for Factor B:** (Number of levels of B - 1) = (3 - 1) = 2* **Degrees of freedom for Interaction (A x B):** (Degrees of freedom for A) * (Degrees of freedom for B) = 2 * 2 = 4
