Question #1 (50pts)

In a study about dieting and weight loss, N=80 subjects were gathered to participate. All of the participants were approximately 20-25% overweight (from their ideal weight), with no habits of exercising. The researchers randomly assigned these participants into four different categories: participants in Category I (N=20) ate the traditional low-caloric diet, participants in Category II (N=20) ate the ketogenic diet, participants in Category III (N=20) were told to eat whatever they want as if they were not on a diet at all, and participants in Category IV were ate an intermittent fasting diet. The amount of participant’s weight loss (in percentage) was recorded after 6 weeks of dieting period.

Note: Refer to the excel file in order to calculate some necessary information.

Answer the following questions:

1. Identify the independent variable(s) and their level(s). 2pt

2. Identify the dependent variable. 2pt

3. What type of data is the independent variable(s) (discrete or continuous). 1pt

4. What scale of measurement is the dependent variable? 2pt

5. State the research design of the present study. 4pt

6. Calculate and report the mean, SD, and SEM value. 6pt

7. Using the excel program, generate a figure based on information presented, paste the graph on Word file. Make sure your graph has correct Y & X axes labeling and correct error bars. 10pts

8. Write the corresponding figure caption for the figure you generated. 3pt

9. Describe this study’s data as if you were writing the results section in a lab report. Include all of the following (20pts):




1. Descriptive statistics


2. Inferential statistics (with posthoc, if applicable)

Question #2 (50pts)

A study was interested in environmental temperature and its relationship(s) with effectiveness of learning, a researcher gathered 15 participants from New York City. The experimenters have three testing conditions for all of these participants, in which all of them were tested in temperatures in one day (40° F, 70° F, 100°F). Participants’ task was to learn a list of 100 words. At the end without any external help, the number of words that participants correctly recalled was recorded for each group.

Note: Refer to the excel file provided in the floppy disk as the raw data set.
