Quizplus · Accepted Answer

The equation used to calculate the Total Variation (SST) is SSA + SSW.
Key Takeaway: Total variation of the individual data values across the various machine settings is variation among the sample factor means (SSA) and variation that exists among the data values within a particular factor level (SSW).
