This lesson focuses on scatter plots and lines of best fit. Students begin by making a line graph to examine data over time. They then identify scatter plots as having positive, negative, and no correlation. They work with lines of best fit, or trend lines, and study cautions about their use when making predictions. Student conclude the lesson by drawing a line of best fit using the mean values of the variables as one point, and estimating an appropriate line through this point.
