Question

I submitted this earlier with incorrect info. Can you please walk me through this problem. I want to confirm that I'm on the right track. Thanks.

Data represent the effects of food and/or water deprivation on behavior. Treatments 1 and 2 represent control conditions; animal received ad lib food and water (1) or else food and water twice per day (2). In treatment 3 animals were food deprived, in treatment 4 they were water deprived, and in treatment 5 they were deprived of both food and water. The dependent variable is the number of trials to reach a predetermined criterion. Assume we compared the combined control groups (treatments 1 and 2) with the combined experimental groups, the control groups with each other, the singly deprived treatments with the doubly deprived treatment, and the singly deprived treatments with each other.

Fill out the table below based on the comparisons (linear contrasts)

2. Interpret the results for Contrast 1.
3. Taking into account all four contrasts, what do the results tell us about the effect of food/ water deprivation on the learning task?
