3 questions

Note from the author:

Here are six proposed studies for investigating the question of the day. 
Suppose we found that the mean SAT score of students who took an SAT prep course is significantly higher than the mean SAT score of students who didn’t take an SAT prep course. 
What conclusions could we make?

Instructions

Here are six proposed studies for investigating the question of the day. 
Suppose we found that the mean SAT score of students who took an SAT prep course is significantly higher than the mean SAT score of students who didn’t take an SAT prep course. 
What conclusions could we make?

Required

For the studies below, match with whether or not there is RANDOM ASSIGNMENT.
Remember: random assignment MUST be present to show causation.

Select a random sample of Seniors from your school to participate in a study. Ask them whether or not they took an SAT prep course and divide them into two groups based on their answer to this question.
Select a random sample of Seniors from your school to participate in a study. Randomly assign half of the students to take an SAT prep course and have the remaining half not take an SAT prep course. Then have both groups take the SAT again.
Select a random sample of students who have taken the SAT from your school to participate in a study. Randomly assign half of the students to take an SAT prep course and have the remaining half not take an SAT prep course. Then have both groups take the SAT again.
Get all the students in a senior-only class to participate in a study. Ask them whether or not they took an SAT prep course and divide them into two groups based on their answer to this question.

RANDOM ASSIGNMENT IS PRESENT
Random Assignment is NOT present

For the studies below, match with the corresponding conclusion that can be made.
Read carefully to determine the population that is being represented.

Remember:  
random sample allows you to generalize to the population from which it was taken
random assignment allows us to show causation

Select a random sample of Seniors from your school to participate in a study. Randomly assign half of the students to take an SAT prep course and have the remaining half not take an SAT prep course. Then have both groups take the SAT again.		For the students in this class there is an association between taking an SAT prep course and higher SAT scores

Ask them whether or not they took an SAT prep course and divide them into two groups based on their answer to this question.		For all seniors at your school, taking an SAT prep course causes higher SAT scores.
