- Describe a research question where it makes sense to use
- an independent t-test
- a single sample t-test
- a dependent t-test
Homework Answers
An independent t test is used where you compare two groups on one single attribute.
Example: the average height of men and women. Say, you want to compare if the average height of men is greater than that of women, then you will use the independent t test
A single sample test is used to check if the certain values have a pre defined mean or not
Example: You want to check if the average height of males of your locality is 73 inches or not, then you will use single sample t test.
An dependent t test is used where you compare two related groups on one single attribute.
Example: the average height of men and their sons. Say, you want to compare if the average height of men is greater than that of their respective, then you will use the dependent t test

Identify the independent and dependent variables of your research design, including the levels of the independent variable. 3. Describe what an alpha level is, and what the alpha level's relationship is to the null hypothesis in the specific context of your research study. 4.

Explain when you would you use a dependent samples t-Test rather than an independent sample t-Test? What are the benefits and problems with each design? Be specific! Using similar IVs and DVs, design a study that uses a dependent samples t-Test design and a study that uses an independent samples t-Test (base them on the same general topic – this can be any topic, not just the “how fast” topic)). Make sure to note your independent and dependent variables for...
