In a completely randomized experimental design involving five treatments, 13 observations were recorded for each of the five treatments (a total of 65 observations).Also, the design provided the following information. SSTR $= 200$ (Sum of Squares Due to Treatments)
SST $= 800$ (Total Sum of Squares)
The sum of squares due to error (SSE) is
A) 1000.
B) 600.
C) 200.
D) 1600.

Question

In a completely randomized experimental design involving five treatments, 13 observations were recorded for each of the five treatments (a total of 65 observations).Also, the design provided the following information.  SSTR $= 200$ (Sum of Squares Due to Treatments)
SST $= 800$ (Total Sum of Squares)  
The sum of squares due to error (SSE) is
A) 1000.
B) 600.
C) 200.
D) 1600.

Quizplus · Accepted Answer

SSE is calculated as SST - SSTR. Therefore, SSE = 800 - 200 = 600.

In a Completely Randomized Experimental Design Involving Five Treatments, 13 =200= 200=200

In a Completely Randomized Experimental Design Involving Five Treatments, 13 $= 200$
