1. Using the survey that you
constructed in the Module 3 Workshop, identify a nominal, ordinal, and
continuous variable: write out each example of the question with variable
levels with choices from your survey. Identify the appropriate measures of
central tendency for each type of variable (mode, median, mean).
2. Identify 2 variables in your Module 3 Workshop
survey that you would like to check for a correlation. What correlation
statistic would you use (lambda, gamma, Pearsons’)? Why?
3. Define validity and reliability and explain why they are
important in the research process.
4. Differentiate between causation and correlation.
5. Explain the meaning of statistical significance and why
it is important.
6. What is a spurious correlation? Give an example and
explain why it is a spurious correlation.
