Statistics

Question: The person designing the study of Exercise, aimed at determining the didactic benefits of computer activities, can make one of the two choices:

(i) make sure that the students know which of the two sections will be taught with computer activities, so they can make an informed choice, or

(ii) not make available any information regarding the teaching method of the two sections. Which of these two choices provides a closer approximation to simple random sampling?

Exercise: In an effort to determine the didactic benefits of computer activities when used as an integral part of a statistics course for engineers, one section is taught using the traditional method, while another is taught with computer activities. At the end of the semester, each student's score on the same test is recorded. To eliminate unnecessary variability, both sections were taught by the same professor.

(a) Is there one or two populations involved in the study?

(b) Describe the population(s) involved.

(d) What is (are) the sample(s) in this study?
