Question Set 1: Completing an ANOVA Source Table
A group of researchers wants to measure the difference between the cost of different fruits from six grocery stores in the USA (Walmart, Target, Weis, Schnucks, Trader Joe, and Aldi). Complete the enclosed ANOVA table to help researchers determine the difference between costs. Round all answers to 3 decimal places(except DF).
Source of Variation | Sum of Squares (SS) | Degrees of Freedom (DF) | Mean Square (MS) | F-statistic |
---|---|---|---|---|
Factor (i.e. BetweenGroups) | 35.957 | 5 | ? | ? |
Error (i.e. Within Groups) | 322.384 | ? | ? | |
Total | 358.341 | 261 |
- df Within Groups (i.e. df Error) = - =
- MS Between Groups (i.e. MS Factor) = / =
- MS Within Groups (i.e. MS Error) = / =
- F statistic = / =
Source | SS | df | MS | F-value |
