In one-way ANOVA, which of the following statements are true?
A) SST is a measure of the total variation in the data.
B) SSE measures variation that would be present within treatments even if $H _ { o }$
Were true, and is thus the part of total variation that is unexplained by the truth or falsity of $H _ { o }$
)
C) SSTr is the amount of variation between treatments that can be explained by possible differences in the population or treatments' means.
D) If explained variation is large relative to unexplained variation, then $H _ { o }$

All of the statements accurately describe aspects of one-way ANOVA. A) SST represents the total variation in the dataset. B) SSE is the error sum of squares, indicating variation within groups that is not explained by the treatment effects. C) SSTr measures the variation between group means, which could be due to treatment effects. D) A large ratio of explained to unexplained variation (SSTr/SSE) suggests that the null hypothesis ($H_0$) should be rejected, indicating significant treatment effects.
