• Question 340:

  Calculate the main effect of factor A:

  

  A. 20

  B. 25

  C. 30

  D. 40

  E. none of the above

  Correct Answer: A

  Explanation: A factorial experiment can be analyzed using ANOVA or regression analysis[ citation needed]. It is relatively easy to estimate the main effect for a factor. To compute the main effect of a factor "A", subtract the average response of all experimental runs for which A was at its low (or first) level from the average response of all experimental runs for which A was at its high (or second) level.
