Question: Consider the 262 design in Table 14-29. (a) Suppose that after analyzing the original data, we find that factors C and E can be dropped.
Consider the 262 design in Table 14-29.
(a) Suppose that after analyzing the original data, we find that factors C and E can be dropped. What type of 2k design is left in the remaining variables?
(b) Suppose that after the original data analysis, we find that factors D and F can be dropped. What type of 2k design is left in the remaining variables? Compare the results with part (a). Can you explain why the answers are different?
