Which of the following correctly describes the F statistic for the completely randomized design?
a. It equals the ratio of mean squares for treatments (MST) to mean squares for error (MSE).
b. It equals the ratio of sum of squares for treatments (SST) to sum squares for error (SSE).
c. It equals the ratio of sum of squares for error (SST) to total sum of squares (Total SS).
d. All of these.
e. None of these.
Question 2
Which of the following correctly describes the treatment sum of squares in one-way ANOVA?
a. It equals the sum of the squared deviations between each treatment sample mean and the grand mean, multiplied by the number of observations made for each treatment.
b. It equals the sum of the square deviations between each block sample mean and the grand mean, multiplied by the number of observations made for each block, multiplied by the number of observations per cell.
c. It equals the number of rows (or columns) multiplied by the sum of the squared deviations of the column-block sample means from the grand mean.
d. It equals the number of columns (or rows) multiplied by the sum of the squared deviations of the row-block sample means from the grand mean.
e. None of these.
