The following Excel output for = 0.01 summarizes a portion of the results for a randomized block experiment without interaction where factor A (column) represents three income categories (low, medium, high), factor B (rows) consists of three different kinds of political parties (Democrat, Republican, Independent), and the variable measured was the amount (in $) contributed to the political party during the 2008 presidential election.
Find the missing values in the ANOVA table. (Round your answers except \"df\" to 2 decimal places.)
| ANOVA | ||||||
| Source of variation | SS | df | MS | F | p-value | F crit |
| Rows | 43,061.29 | 3 | MSB = | FFactor B = | 0.0010 | 12.0600 |
| Columns | 15,374.15 | 3 | MSA = | FFactor A = | 0.0150 | 12.0600 |
| Error | 2,537.79 | 5 | MSE = | |||
| Total | 60,973.23 | 11 | ||||
Solution
On the MS column:
MSB = SS(row)/df(row) = 14353.76
MSA = SS(columns) / df(columns) = 5124.72
MSE = SS(error)/df(error) = 507.56
*****************
On the F column,
F(B) = MSB / MSE = 28.28
F(A) = MSA / MSE = 10.10
