Please indicate the type of test needed to analyze the data described. Review the lessons on identifying variables and their levels and use the flow chart to help you. Take your time and go through each step in the flow chart for each scenario, considering factors such as: 

1. Are you comparing groups or time points? Or just examining a relationship? 
2. What type of experimental design is it? 
3. At what level of measurement are the data (nominal, ordinal, interval, ratio)? 
4. If there is a true IV, how many levels does it have? 
5. If it is an experimental design, is it between-subjects or within-subjects? 

The following answers may be used more than once. 

 a. Chi-square

b. Correlation

c. Regression

d. Independent samples t-test

e. Paired samples t-test

f. One-way ANOVA  

g. Repeated measures ANOVA 

h. Between-subjects factorial ANOVA 

i. Repeated-measures factorial ANOVA 

Match the letter with the number:

1. You divide research participants into two groups. Group A drinks three non-alcoholic drinks and Group B drinks three alcoholic drinks. You compare the groups' spatial task scores. 
2. You are interested in determining whether individuals who identify as Republican are more likely to favor term limits for senators ("Do you support term limits for senators, yes or no?") than are individuals who identify as Democrats. 
3. A group of football players will be measured on their stress level during two practice times: morning and evening. Additionally, stress measurements will be compared before and after each practice session.  
4. You want to know whether allowing shelter dogs visual access to other dogs affects the amount that they bark. You compare barking before giving the dogs visual access, during visual access, and after visual access.    
5. You want to know if there is a relationship between the average number of laps people walk at a local, outdoor track and the temperature outside.  
6. 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. 
7. 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 are compared. 
8. You want to know if you can predict how students will do on the final exam using their scores on exams 1 through 3 and the number of days they have been absent during the semester.  
9. You are studying the effects of environmental enrichment on cortisol levels in rats. You divide your rats into 4 groups: 1. Music and no paper tunnel; 2. Music and paper tunnel; 3. No music and no paper tunnel; 4. No music and paper tunnel. You compare cortisol levels after 2 weeks of exposure. 
10. You are studying the effect of level of processing on word recall. Each student is shown two lists. The instructions on the list differ, with one requiring shallow processing and the other requiring deep processing. You want to compare the number of words recalled in the shallow and deep processing conditions.
