In employing the randomized block design,the expected effect is to:
A) increase the treatment sum of squares (SSTR).
B) reduce the error sum of squares (SSE).
C) improve the significance of any differences within the treatment groups.
D) reduce the total sum of squares (SST).
E) increase the error sum of squares (SSE).

Question

Quizplus · Accepted Answer

Randomized block design reduces the variability caused by extraneous factors by dividing the experimental units into homogenous blocks. This results in a reduction in the error sum of squares (SSE) and increased efficiency in detecting treatment effects. Therefore, choice B is the correct answer.
