Hello All,

Imagine we have two groups of students in a school: group A and group B.

The distribution of these two groups of students in each class (CLASS)
nested in each course (COURSE) is shown below (*the actual data is larger*).

**QUESTION: I was wondering if there is a mixed method technique to answer
the following questions:

1- Overall, is a significantly larger group A vs. B students found in the
data?

2- For each course, is a significantly larger group A vs. B students found
in data?

Warm Regards,
Simon
