Hi, guys. I met a phrase, a difference across, which I don't understand.
a difference across, here, equal "a difference involved in diets" or "a difference with regarded to diets" ??
Thanks in advance.

In the following example we are testing if there is a difference across diets between the differences of exertype group 1 and 2 versus exertype group 3. This kind of contrast is known as an interaction contrast and for more details about these type of interactions please refer to Design and Analysis by G. Keppel. From the results we see that there is indeed a significant differences across diets between exertype group 1 and 2 and exertype group 3 (p = 0.004).
