Question

a professor wants to study the effectiveness of a new study tool for a course. there are 150150150 students registered for the course. the professor ranks the students according to cumulative average in the prerequisite course. for every 222 students, in order, from the list, the professor flips a coin to assign one student to use the new study tool and the other to use the previous study tool. what type of experiment design is this?

Answer 1

This is a matched-pairs design experiment where the professor ranks the students and pairs them for random assignment to different study tools.

Step-by-step explanation:

This is an example of a matched-pairs design experiment. In this experiment, the professor is using the ranks in the prerequisite course to create pairs of students that are similar in terms of their academic performance. The pairs are then randomly assigned to either the new study tool or the previous study tool. By using this design, the professor can compare the effectiveness of the two tools while controlling for potential confounding variables.
