Determine whether the sampling is dependent or independent. Indicate whether the response variable is qualitative or quantitativ
Papessa [141]

Answer:

Dependent.

Quantitative.

Step-by-step explanation:

<u>Determine whether the sampling is dependent or independent.</u>

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.
