1. Scenario: Suppose participants complete an experiment where ads are presented subliminally during a task (e.g., Pepsi ads are flashed at a very fast rate during movie ads). Participants are then given a recognition test for images of the ads, where two images are presented and participants must choose which one of the two was presented earlier. Both men and women (18 of each gender) participate in the study, and the researcher predicts that recognition accuracy (0 " 100%) will differ based on gender. Question: Which of the following best describes the research design?

a. Descriptive

b. Predictive

c. Quasi-experimental

d. experimental

2. Scenario: A researcher wants to know whether a hard copy of a textbook provides additional benefits over an e-book. She conducts a study where participants are randomly assigned to read a passage either on a piece of paper or on a computer screen. After a distractor task lasting 30 minutes, the participants are tested for their comprehension of the passage with a multiple-choice test containing 10 questions about their passage. Comprehension was scored using percent correct (0 " 100%). The researcher predicts that those randomly assigned to read the passage on a piece of paper will remember significantly more than those who read the passage online. Question: What is the research / alternate hypothesis for this scenario?

a. People who read a passage on a piece of paper will remember more than those who read a passage online.

b. People who read a passage on a piece of paper will not remember more than those who read a passage online.

c. Amount remembered of a passage will vary based on whether people read the scenario on a piece of paper verses online.

d. Amount remembered of a passage will not vary based on whether people read the scenario on a piece of paper verses online.

3. Scenario: A researcher wants to see whether ESP abilities in psychics differ based on environment. Thus, the researcher has psychics predict card suits in both a fortune-telling environment (e.g., low lighting, candles, a crystal ball), and in a standard lab environment. They complete 100 trials of the task in each environment, with the environment type counterbalanced between participants. All 30 psychics completed the card prediction task in both environments. Accuracy rates are compared. Question: As taught in 510/515, what is the most appropriate graph to illustrate this scenario?

a. Scatterplot

b. Clustered bar graph

c. Bar graph

d. Box plot

4. Scenario: A researcher wants to see whether ESP abilities in psychics differ based on environment. Thus, the researcher has psychics predict card suits in both a fortune-telling environment (e.g., low lighting, candles, a crystal ball), and in a standard lab environment. They complete 100 trials of the task in each environment, with the environment type counterbalanced between participants. All 30 psychics completed the card prediction task in both environments. Accuracy rates are compared. Question: What is the most appropriate statistical test to conduct given this scenario?

a. Independent samples t-test

b. Correlated groups t-test

c. Pearsons r correlation

d. Phi correlation

5. Scenario: A researcher wants to see whether ESP abilities in psychics differ based on environment. Thus, the researcher has psychics predict card suits in both a fortune-telling environment (e.g., low lighting, candles, a crystal ball), and in a standard lab environment. They complete 100 trials of the task in each environment, with the environment type counterbalanced between participants. All 30 psychics completed the card prediction task in both environments. Accuracy rates are compared. Question: Which of the following best describes this scenario?

a. It is one-tailed; directional.

b. It is two-tailed; non-directional.

c. It is one-tailed; non-directional.

d. It is two-tailed; directional.

6. Scenario: Does studying with background music (X) improve test scores (Y)? Students self-reported whether or not they listened to background music (Yes or No), and the last score the earned on an exam (0-100%). Question: What is the most appropriate statistical test to conduct given this scenario?

a. Pearsons r correlation

b. Spearman correlation

c. Point Biserial correlation

d. Phi correlation

7. Scenario: Does studying with background music (X) improve test scores (Y)? Students self-reported whether or not they listened to background music (Yes or No), and the last score the earned on an exam (0-100%). Question: What is the scale of measurement for variable Y in this scenario?

a. Nominal

b. Ordinal

c. scale

8. Scenario: Is there a relationship between anxiety (X) and belief in God (Y)? A researcher had participants self-report their anxiety as low, moderate, or high. Participants also reported their belief in God as non-existent, belief but unsure, belief but weak, or strong belief. Question: What is the scale of measurement for variable Y in this scenario?

a. Nominal

b. Ordinal

c. Scale

9. Scenario: Is there a relationship between worker type (X) and productivity (Y)? The researcher defined worker type (X) as blue or white collar, and productivity (Y) as high or low. Question: What is the most appropriate statistical test to conduct given this scenario?

a. Pearsons r correlation

b. Spearman correlation

c. Point Biserial correlation

d. Phi correlation

10. Scenario: Is there a relationship between amount of time at a job (X) and productivity (Y)? The researcher quantified amount of time at a job by ranking the employees from those who had been there the least amount of time to the most. The researcher quantified productivity as rating the employees from best to worst. Question: What is the scale of measurement for variable Y in this scenario?

a. Nominal

b. Ordinal

c. scale

11. If a teacher wants to assess whether there is a difference between males and females on test performance, the most appropriate graph based on 510/515 would be:

a. scatterplot

b. clustered bar graph

c. bar graph

d. box plot

12.If a teacher wants to assess whether positive feedback impacts test performance and she assesses test performance at the beginning and end of a semester in a single group of students, the most appropriate graph (as presented in 510/515) would be:

a. scatterplot

b.clustered bar graph

c. bar graph

d. box plot
