An educator wants to determine whether a new curriculum significantly improves standardized test scores for students. she randomly divides 70 students into two groups. group 1 is taught using the new curriculum, while group 2 is taught using the traditional 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

Solution: An educator wants to determine whether a new curriculum significantly improves standardized test scores for students. she randomly divides 70 students into two groups. group 1 is taught using the new curriculum, while group 2 is taught using the traditional 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

The given sampling is independent.

And the response variable is quantitative.

Independent

Quantitative.

Step-by-step explanation:

A variable is called quantitative when it's result is a value, for example, a value between 0 and 100. Otherwise, if the results are concepts, for example grade A,B,C,D,F, it is qualitative. In this case, the mean test scores are compared, and the mean is quantitative. So the response variable is quantitative.

Also, the result of the group 1 has no impact on the result of the group 2, that is, the mean of these groups do not impact each other. So the samplings are independent.
