Procedures

A scatter plot shows a positive linear association between two
variables. Four students each draw a different straight line through
the data. Which line is the best informal line of fit?

A line that passes exactly through the two highest data points, leaving most other points below it.

A line that follows the upward trend with roughly equal numbers of points above and below it, staying close to the data.

A horizontal line drawn through the average height of all the points.

A line that connects the first data point to the last data point in order.
