A researcher computes the computational formula for SS and finds that and .If this is a sample of 6 scores,then what would SS equal using the computational formula?
A) 17.5
B) 3.5
C) 232
D) not possible to know because the sample mean is not given

Question

Quizplus · Accepted Answer

The computational formula for SS is SS = Σ(X - X̄)², where X is each score and X̄ is the sample mean. If the sample mean is not given, then it is not possible to calculate SS using the computational formula. However, if the sample mean is given, then SS can be calculated using the computational formula. In this case, the sample mean is not given, so it is not possible to calculate SS using the computational formula.
