True or False Questions:
1. In one-factor ANOVA, the total sum of squares can be
separated into the sum of squares of treatments and sum of square
of error. T/F?
2. The mean sum of square of factor over the mean sum of square
of error follows F-distribution. T/F?
3. If the mean sum of square of factor over the mean sum of
square of error is 1, we should reject null hypothesis. T/F?
