Question

An educator wants to determine whether a new curriculum significantly improves standardized test scores for third grade students. She randomly divides 90 third dash graders into two groups. Group 1 is taught using the traditional ​curriculum, while group 2 is taught using the new curriculum. At the end of the school​ year, both groups are given the standardized test and the mean scores are compared. Determine whether the sampling is dependent or independent. Indicate whether the response variable is qualitative or quantitative.

Answer 1

Independent

Explanation:

Dependent Sampling:

Dependent sampling is one in which the individuals in one sample are used to determine the individuals in the other sample.

But the third dash graders are divided into two groups independent of each other.

So the sampling is independent.

It is qualitative because it is showing quality irrespective of the number of students .

Quantitative Sampling is one in which the results change with the number of the individuals / tests etc. But in this experiment the number of the students is fixed so it is showing quality rather than quantity.
