In this activity, you will collect the entire data set for two of the variables so that you can fit a line of best fit for the two variables.
Justify which variable you chose to be the independent variable and which you chose to be the dependent variable.
Create a scatter plot with a line of best fit.
Interpret the slope and y-intercept as in the examples from this activity.
Interpret the correlation coefficient as in the examples from this activity.
Make any overall conclusions from the data.
You could use any spreadsheet you would like. Desmos.com is another great option for scatter plots.
