Questions 1 - 2:

1. Dr. Meow teaches Engineering Science 101 and is interested in finding out whether her students perform better on math tests compared to all of the engineering students in the university. State this as a null hypothesis and research/alternative hypothesis. (2 pts)
2. Dr. Moo would like to find out if his daisies grow at a faster average rate than the average rate of daisy growth in his neighborhood. State this as a null hypothesis and research/alternative hypothesis. (2 pts)

Questions 3 - 5: Remember that a hypothesis is a short, declarative statement (NOT a question) that provides a tentative explanation for a phenomenon):

Assuming a hypothetical college campus - Do people walking alone walk faster than people walking in groups (two or more)?

3. State the null hypothesis (2 pts)

4. State an alternative/research hypothesis (2 pts)

5. Identify your independent/subject variable and your dependent variable (2 pts)

Questions 6 - 8: Remember that a hypothesis is a short, declarative statement (NOT a question) that provides a tentative explanation for a phenomenon):

Assuming a hypothetical college campus - Which campus building has more traffic (people going in and out)?

6. State the null hypothesis (2 pts)

7. State an alternative/research hypothesis (2 pts)

8. Identify your independent/subject variable and your dependent variable (2 pts)

9. What is the difference between reliability and validity? (1 pt)

10. Can a measure be reliable but not valid? Explain. Can it be valid but not reliable? Explain. (1 pt)

11. Describe the differences between content-based, criterion-based, and construct-based validity. Give examples of how each of these is measured. (6 pts)
