Part Two: Representation of Data with Plots
Using graphing software of your choice, create a scatter plot of your data. Predict the line of best fit, and sketch it on your graph.
Copy and paste your scatter plot into a word processing document.
Part Three: The Line of Best Fit
Include your scatter plot and the answers to the following questions in your word processing document (JUST PUT THE DATA INTO A SCATTER PLOT GENERATOR ONLINE, I CAN COPY AND PASTE IT IN HERE)

1.Which variable did you plot on the x-axis, and which variable did you plot on the y-axis? Explain why you assigned the variables in that way.
2.Write the equation of the line of best fit using the slope-intercept formula y = mx + b. Show all your work, including the points used to determine the slope and how the equation was determined.
3.What does the slope of the line represent within the context of your graph? What does the y-intercept represent?
4.Test the residuals of two other points to determine how well the line of best fit models the data.
5.Use the line of best fit to help you to describe the data correlation.
6.Using the line of best fit that you found in Part Three, Question 2, approximate how tall is a person whose arm span is 66 inches?
7.According to your line of best fit, what is the arm span of a 74-inch-tall person?
