Correlation Project
Details:As a researcher, you will be considering the relationships between variables regularly. Linear correlation is the most basic relationship that may exist between two variables. This assignment will you give the opportunity to see how statistics can start to answer the research questions you will be faced with in your field of study.
Correlation Project Directions:
Consider a possible linear relationship between two variables that you would like to explore.
- Define the relationship of interest and a data collection technique.
- Determine the appropriate sample size and collect the data.
- Perform the appropriate analysis to determine if there is a statistically significant linear relationship between the two variables. Describe the relationship in terms of strength and direction.
- Construct a model of the relationship and evaluate the validity of that model.
