Question

Classify each as independent or dependent (matched pair data)

Test scores of the same students in English and psychology.

What about using different students?

Answer 1

Test scores of the same students in English and psychology.

It is an example of dependent data

Since the test scores are of the same student, thus we have a dependent data. This is as there is generally a trend that a hard working student would perform equally well on both tests. There is a strong dependency between the scores of the test.

If we use different students that would be independent data

Score of a student in english would not have any impact on the score of another student in psychology.
