In this lesson, we will learn how to draw a straight line of best fit for a scatterplot, where appropriate, and use this to interpret and make predictions about the data.
Students will be able to
Q1:
Which line fits the data graphed?
Q2:
The following scatterplot shows the heights and weights of 24 students in a class. Use the scatter graph to determine which of the following would be the best estimate for the weight of a person who has a height of 150 cm.
Q3:
How useful would a line of best fit be for this scatterplot?
