_________ A researcher is interested in finding out if the color of the classroom affects performance on a memory test. He randomly assigns 10 students to a classroom with green walls, 10 students to a classroom with purple walls, and 10 students to a classroom that has neutral colored walls (typical classroom). After the students are all assigned to their rooms they are given the memory test and scores are determined.

_________ A new drug is being tested to determine its effectiveness for decreasing depression. A group of participants are measured on depression levels before and after receiving the drug. Scores before and after were compared.

_________ Dr. Williamson wants to determine if the GPA of students in her experimental psychology class is significantly higher than the average GPA of all college students attending KSU in the same semester. The mean of all college students enrolled at KSU in the fall semester of 2008 is 2.9 and the SD is .3

. _________ Faculty teaching Experimental Psychology want to know if the statistics ability of KSU graduates differ from the national average. They know that the average on the national statistics exam is 5.8

Independent Measures t-test

A new drug is being tested to determine its effectiveness for decreasing depression. A group of participants are measured on depression levels before and after receiving the drug. Scores before and after were compared.

Dependent Measures t-test

Dr. Williamson wants to determine if the GPA of students in her experimental psychology class is significantly higher than the average GPA of all college students attending KSU in the same semester. The mean of all college students enrolled at KSU in the fall semester of 2008 is 2.9 and the SD is .3

z-test

Faculty teaching Experimental Psychology want to know if the statistics ability of KSU graduates differ from the national average. They know that the average on the national statistics exam is 5.8
