1. Provide examples of (a) univariate data and (b) bivariate data. What is it about each example that makes it an appropriate example of the data type?

2. Describe a scenario where the Pearson correlation would be appropriate to use in calculating the strength of the relationship between two variables. Identify the variables and the measurement level of the data and explain why the variables are appropriate for use with the Pearson correlation.

3. Describe a scenario where the Spearman correlation would be appropriate to use in calculating the strength of the relationship between two variables. Identify the variables and the measurement level of the data and explain why the variables are appropriate for use with the Spearman correlation.

4. Describe an example of the third variable problem in correlation. Describe the variables and explain the relationships between them.

5. Describe at least one limitation of using regression equations to make predictions about outcomes. Include an example to illustrate this.
