Example of a Contrast Codes Table
 back to Proposal Info     -     back to 7670 homepage

If you are testing a prediction that involves planned contrasts, then your proposal should have
a contrast codes table. When you put together a contrast code table, you should do two things.
First, you should make sure your contrasts are orthogonal, in that, they sum to zero. Second,
you should be able to determine easily what the contrasts are comparing. For example:

        1. Compares the depression ratings for participants classified as collectivists or individualists.
        2. Compares the depression ratings for participants in the ability-lower condition against
            those in the ability-same and ability-higher.
        3. Compares depression ratings for participants classified as collectivists or individualists in
            the opinion-disagree condition.
        4. Compares depression ratings for participants classified as collectivists or individualists in
            the ability-higher condition.
