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.
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.
