Would the interaction (source*amount) in the table below be significant since the p-value (0.0545) is close to 0.05?
Source | DF | Type I SS | Mean Square | F Value | Pr > F |
source | 1 | 220.900000 | 220.900000 | 0.99 | 0.3269 |
amount | 1 | 1299.600000 | 1299.600000 | 5.81 | 0.0211 |
source*amount | 1 | 883.600000 | 883.600000 | 3.95 | 0.0545 |
Decisions about what will be considered significant result levels, test statistic or p-value ranges, should be made before the test is run.
But source is not significant , I would only keep amount .
