Hi Ketone,

What are the three groups?

Do you compare the three groups? or each group to the same group in different situation? (like before taking the medicine, 1 day after medicine. 5 days after medicine)

What are the differences between the 3 groups? I assume the control didn't have any interaction? What is the difference between the two groups?

If 4 is it always 1 week after?

Example:

Control: 50, 50, 50, 50, 50, 50, 50, 50,

Group1: 50,

Group2: 50, 50,

If so, do you expect to get the same result on Group1 week2 (n) and group2 week3 (n+1)?

What do you compare between the groups?

The one way ANOVA, may compare if the difference of the averages of sample groups is significant.

But I still don't understand the research.

What are the differences between the 3 groups? say what cause to the change in the intake?

I assume the reduction increase over time? and then become constant? then you can run the test only on the last day to see id the difference is significant. (if the test power is strong enough, otherwise you may need to group days).

If it is significant for the last day and insignificant for the first day you may need to continue day2 day3 until getting a significant result.

But since you run multiple tests you may get significant results in day 5 and insignificant results in day6.
