Jermaine is curious if the way students take notes affects their academic ability. jermaine recruits two groups of students from classes on campus: one group of high achievers and one group of low achievers. he then asks both groups to take notes in the exact same way to see how it will affect their scores. during the study, several students in the low-achieving group drop out from the study, as they find the note-taking task difficult. at the end of the study, the results for each group are similar. (only members of a particular group dropped out of the study)

what threat to internal validity may be present?

The correct answer is the selection attrition threat.

Explanation:

In investigations involving two or more groups, they may encounter difficulties with internal validation threats.

For example, in this case, there is a validation threat that is the selection attrition threat. When a selection attrition risk occurs, the internal validity of the investigation is affected because the participants leave the process before the study ends.

And in this study, the results were similar, this is because in one of the groups, they abandoned members, and this leads to the validity of the study is at risk.

I hope this information can help you.

the answer might be either a or c. can't be too sure , because i searched the web, but no valid answers came through.
