Answer:
As in explanation.
Step-by-step explanation:
A) SSE means "Error Sum of Squares". The source of it is the sum of squared deviations within groups.
B) SSTR means "Treatment Sum of Squares". It's source is the weighted sum of squared deviations of group means from grand mean. It's the sum of squares between groups.
C) SST means "Total Sum of Squares''. It's source is total sum of squared deviations from the grand mean. It is a sum of SSE and SSTR.
The source of variation and the naming of each sum of squares is as follows:
A) SSE means "Error Sum of Squares". The source of it is the sum of squared deviations that lies within groups.
B) SSTR means "Treatment Sum of Squares". It's source that represents the weighted sum of squared deviations of group means from the grand mean. It's the sum of squares between groups.
C) SST means "Total Sum of Squares''. It's source that represents total sum of squared deviations from the grand mean. It is a sum of SSE and SSTR.
