Answer:
Dependent.
Quantitative.
Step-by-step explanation:

This is a matched-pair data test, as the same students are measured two times in order to compare the results.
This type of samples are dependent, as they are correlated between them.
<u>Indicate whether the response variable is qualitative or quantitative.</u>
The response variable is the test score. This is a quantitative variable, as this can be defined by a number. Both sample scores are averaged and compared.
