Question 12

An educator wants to determine whether a new curriculum significantly improves standardized test scores for third grade students. She randomly divides 80 third-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 sample is dependent or independent. Indicate whether the response variable is qualitative or quantitative.

Determine whether the sampling is dependent or independent.

The sampling is independent because the individuals selected for one sample do not dictate which individuals are to be in a second sample.

The sampling is dependent because the individuals selected to be in one sample are used to determine the individuals to be in the second sample.

The sampling is independent because the individuals selected to be in one sample are used to determine the individuals to be in the second sample.

The sampling is dependent because the individuals selected for one sample do not dictate which individuals are to be in a second sample.

Indicate whether the response variable is qualitative or quantitative.

The variable is qualitative because it is a numerical quantitative.

The variable is qualitative because it is an attribute classification.

The variable is quantitative because it is a numerical measure.

The variable is quantitative because it is an attribute classification.

Solution

Is the following independent or dependent sampling? Why?

A researcher wishes to compare personality types of lawyers and non-lawyers. She obtains a random sample of 217 professionals of each category who take a personality inventory and determines each individual\'s personality type.

Group 1 is taught using the traditional curriculum, while group 2 is taught using the new cirriculum. At the end of the school year, both groups are given the standardized test and the mean scores are compared.
