A researcher is evaluating customer satisfaction with the service and coverage of two phone carriers. Each individual in a sample of n = 25 uses one carrier for two weeks and then switches to the other. Each participant then rates the two carriers. The following table presents the results from the repeated-measures ANOVA comparing the average ratings. Fill in the missing values in the table. (Hint: Start with the df values.)
Source | SS | df | MS | |
Between treatments | _____ | ______ | 2 | F =_____ |
Within treatments | ______ | __________ | ||
Between subjects | ______ | ______ | ||
Error | 12 | _______ | ________ | |
Total | 23 | _______ |
To find: The missing values in the table.
Given info:
The data on customer satisfaction of 2 phone carriers regarding service and coverage has number of individuals in sample,
The available values in the repeated-measures ANOVA table are:
Calculation:
Formula for N:
The total degrees of freedom (df) is:
Now, mean of squares of a factor w is:
