Answer:

independent groups design.

Explanation:

In independent groups design, the researchers will put different subjects/participants for each different tests on the research. (this is why the students are separated to low level group and high level group.)

Typically, this type of study is being done to find for two reasons:

1. To find out a how different external occurrences can influence the condition of a certain variable.

2. To accelerate the research process. Separating the group will be faster compared to testing each test one by one.
