Paper details

The practice activity contains questions about quantitative analysis.

1. Describe three common indications of central tendency and say what the limitations of each are. Provide an example of each.

2. What is the difference between parametric and non-parametric numbers? Give an example of each and explain the impact of the difference in data analysis (e.g. the number of subjects needed to get the same statistical power, etc.).

3. What is a “power analysis” and what is it used to predict?

4. What is the difference between descriptive and inferential statistics? Give an example of each and explain what the strengths of each are.

5. Describe the concept of “significance” levels in relation to odds.

6. Differentiate between statistical and real (e.g. clinical) statistical significance.
