The equation for analysis of variance may be expressed as follows:
OPTIONS
- The total standard deviation is equal to the sum of the standard deviation for the treatment effect plus the standard deviation of the random error.
- Sum of Square of Errors between the mean and individual values
- The total sum of squares of deviations from the grand mean is equal to the sum of squares of deviations among treatment means and the grand mean plus the sum of squares of deviation within treatments.
- Average variation of data from mean
ANSWER
The total sum of squares of deviations from the grand mean is equal to the sum of squares of deviations among treatment means and the grand mean plus the sum of squares of deviation within treatments.
EXPLANATION
The equation is Total SS = SST + SSE Total SS = total sum of squares SST = sum of squares among treatments SSE = sum of squares within treatments (error) Answer C correctly captures this.
