Question

Suppose we are comparing three populations (CRD), and have taken a sample of size 9 from each population to determine whether the population means differed. Suppose it turned out that the analysis of variance was found to be significant at alpha = .05 (i.e., H_0 was rejected). Next suppose that we lake each of the data values in the sample where the sample mean was the highest, and add ten units to each of these data values. State whether this would increase, decrease, or leave unaffected the following (or is there not enough information given?), and why: SSTR SSE SST df1 df2 MSTR MSE F p value Would it change your conclusion? If so, why?

Explanation / Answer

In CRD sample mean highest and add 10 units in each data values then values of SSE, SSTR, SST, MSTR, MSE is increases and df1 and df2 remains same F value also increases
