Question
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.
