Before calculating a correlation coefficient, explain why you would create and examine a scatterplot of the relationship. In your response, please discuss (a) linearity (b) homoscedasticity, (c) restriction of range, and (d) the presence of outliers.

Solutions

Expert Solution

doing a scatter plot is necessary for getting a preliminary idea about how the variables are associated. linearity,homoscedasticity, restriction of range, outliers are few factors of a simple linear regression model.

Why is it advisable to generate a scatterplot before computing a correlation coefficient between two variables? Describe how a scatterplot might differ when viewing correlations that represent positive, negative, and no relationship between predictor and criterion variables. Is it possible to have a relation between variables that systematic (i.e., reliable and predictable) yet not linear?
