DSCI-549 Introduction to Computational Thinking and Data Science - University of Southern California

Goals
The purpose of this homework is to practice, for any given research question, how to analyze data and draw conclusions based on the chosen methodology.

Assignment
Complete this assignment in a word document, with sections that correspond to the 5 items below. Then submit it on D2L.

First, for the following hypotheses, first determine if you can use the experimental method or not, and explain your choice. Then, identify the Independent and Dependent Variables (IV and DV). Next, operationalize each variable - how would you operationalize it if you were going to run a study? Finally, tell me what statistical test you will use and why!

1. Hypothesis: Females (gender assigned at birth) are more talkative than males
Can you use the experimental method or not?
If yes, why? If not, why not (is it not practical, ethical, or neither?)
What are your IV and DVs
Whether experimental or correlational, what are your operational definitions for those variables?
What statistical test do you conduct and why?

2. Hypothesis: People learn more when they study in a quiet versus noisy place
Can you use the experimental method or not?
If yes, why? If not, why not (is it not practical, ethical, or neither?)
What are your IV and DVs
Whether experimental or correlational, what are your operational definitions for those variables?
What statistical test do you conduct and why?

3. Hypothesis: Exercising moderately for 30 minutes in a given day helps you sleep better that night
Can you use the experimental method or not?
If yes, why? If not, why not (is it not practical, ethical, or neither?)
What are your IV and DVs
Whether experimental or correlational, what are your operational definitions for those variables?
What statistical test do you conduct and why?
4. Hypothesis: People who believe they will die soon are less likely to delay gratification (i.e., less likely to forgo immediate rewards for larger future gains).
Can you use the experimental method or not?
If yes, why? If not, why not (is it not practical, ethical, or neither?)
What are your IV and DVs
Whether experimental or correlational, what are your operational definitions for those variables?
What statistical test do you conduct and why?

5. Hypothesis: Sex before marriage improves the marriage
Can you use the experimental method or not?
If yes, why? If not, why not (is it not practical, ethical, or neither?)
What are your IV and DVs
Whether experimental or correlational, what are your operational definitions for those variables?
What statistical test do you conduct and why?
