Contextual Interaction between grade and attending a school offering daily PE. Using the model estimates, the average minutes of MVPA per day for male students can be estimated as a function of both grade and attending a school offering PE daily (5 days/week). In Figure 2, the model-based estimates of a male student relative to a hypothetical male student who is grade 9 and attends a school that does not offer PE daily are presented.
