Studies have shown that stress and consumption of a poor diet can impact learning and memory. I want to assess whether or not the consumption of a high-fat diet and chronic stress have significant impacts on learning and memory (as measured through the Morris Water Maze). I have 4 groups in my study: 1) Mice receiving a high-fat diet and being chronically stressed, 2) Mice receiving a high-fat diet and receiving no stress, 3) Mice receiving a control diet and being chronically stressed, and 4) Mice receiving a control diet and receiving no stress. I measure the amount of time it takes for mice to find a hidden platform (lower numbers are better). At an alpha of 0.01, test if there are significant main effects of diet and stress, if there are any interactions, and interpret any interactions appropriately.
