Group 2 - M-Control

Day 3

Day 4

Group 2 - Control-Control

I have several questions:

Since there are no different dosages involved, I am assuming I will

**not**be using ANOVA (?). I am just comparing the two means of food intakes between each treatments.

It should therefore be a

**t-test for difference of two means, dependent samples**(paired t-tests) ?

Would this be deemed a crossover study? I think Day 1 and Day 2 are crossovers; Day 3 and Day 4 are cross overs.

Thus, should I be comparing

- Day 1 against Day 2; Day 3 against Day 4

- All against all?
