The data she would collect would be grouping people depending on how much video games they played.
This however, is not a statistical question. Instead, she should set for example: 1-3 hrs per week, 4-6 hrs, etc. People play different amounts of hours, and so you cannot set a specific number, it must be a "range-of-numbers".
Also the question itself is kinda judging and comparative
so overall, umm... this question isn't really good
A) It is expected that she collects data in a table like follows:
hours played weekly | number of students
0 | 2
1 | 3
2 | 5
... | ...
B) The question is not a statistical question because a single answer is expected. A statistical question would be <em>How many hours do students spend playing video games? </em> and the answer would be the average of the previously collected data.
