1. Create a scatter diagram which shows the trendline (this is the regression line) and provides the coefficient of determination. Reminder, Week 1 hints in the discussion showed how to make a scatter diagram. Also, this is a graph. It needs to have a title which shows both variables and labeled axes. 2. Define coefficient of determination from the graph (r squared). What does this tell you? 3. Define Pearson's Product Moment Correlation Coefficient (r). What does this tell you about how well the data fits the trend?
