- 14.1: Refresh to Prepare
- New statistics, but still the same variables and process.

- 14.2: What do Two Quantitative Variables Look Like?
- Now that you have an idea about looking at two quantitative variables, let's see what they might look like together.

- 14.4: Strength, Direction, and Linearity
- If correlations are like a descriptive statistic, what can they describe?

- 14.5: Hypotheses
- Because we're not talking about relationships between variables, not mean differences, what do our research hypotheses and null hypotheses look like?

- 14.6: Correlation Formula- Covariance Divided by Variability
- Now that you know more about what Pearson's correlation means, let's look at the actual formula.

- 14.7: Practice on Anxiety and Depression
- Wanna practice a Pearson's r calculation when the standard deviations are provided to you?

- 14.8: Alternatives to Pearson's Correlation
- Are there alternatives if Pearson's r doesn't seem right?

- 14.9: Final Considerations
- There are a few final tidbits about correlations that you should know.

- 14.10: Correlation Exercises
- Wanna do some simple practice questions on correlations?
