A professor wants to study the effectiveness of a new study tool for a course. There are 150 students
registered for the course.
The professor assigns each student a number from 1 to
150 and uses a random number generator to assign the
first 75 students selected to use the new study tool. The
remaining 75 subjects are assigned to use the previous
study tool.
What type of experiment design is this?

completely randomized (answer from Khan Academy)

Explanation:

This study is an example of a completely randomized design since each subject is randomly assigned to one of the treatment groups without extra consideration to other variables.
