In the assigned reading from the book Naked Statistics by Charles Wheelan, the author discusses how the assumption that the relationship between an independent variable and the dependent variable is linear is very important for the validity of a particular application of regression analysis. Provide an example of a potentially non-linear relationship between an independent variable and a dependent variable.

In a correlational study, how do you decide which variable is X and which variable is Y? Define each of the following: Positive linear relationship, Negative linear relationship, Non-linear relationship. As the value of r approaches +|- 1, what does it tell you about the following? The consistency with which X values are paired with Y values. The closeness of the Y scores to the regression line. The accuracy with which we can use X to predict Y. What is linear regression used for? For each of the following, indicate whether it is a positive linear, negative linear, or non-linear relationship: Quality of performance increases when mental arousal increases up to an optimal level; after that point, quality of performance decreases as mental arousal increases. The more overweight an individual, the lower their health. As the number of minutes of exercise per week increases, indecisiveness decreases. The number of bears in an area decreases as the area becomes increasingly populated by humans. What variables in an experiment determine whether to use parametric or non-parametric procedures? Why shouldn't you use parametric tests if data violates the assumptions? What type of variables are appropriate to use with chi-square tests?

Give an example of a problem dealing with two possibly related variables (Y and X) for which a linear regression model would not be appropriate. For example, the relationship could be curved instead of linear, or there may be no significant correlation at all. What is the impact of using a linear regression model in this case? What options, other than linear regression, can you see?
