• Find two variables that you think might have a correlation. Find, or create by distributing a survey, a paired data set for the two variables. Why is this data important or interesting?
• Develop a scatterplot. Does the graph show a linear, quadratic, or other polynomic relationship between the variables? Does the data have an exponential or logarithm relationship?
• Find the value of r squared. Interpret the meaning r-squared specifically for your data.
• Find the equation of the regression function and graph the function on your scatterplot.
• Use the regression function to make a prediction for some value in the scope of your data. Do you think this is a good prediction?
• Use the regression function to make a prediction for some value NOT in the scope of your data. Do you think this is a good prediction?
Charts and graphs should be embedded with each question
