Question

When determining slope, data points do not usually fall within a straight line, so you need to draw a _____ line, with as many points above and below the line as possible.

accurate
precise
best fit
correct

Answer 1

you need to draw a best-fit line

Answer 2

The correct option is 3.

Explanation:

If a straight line passes through some of the points, none of the points, or all of the points of a scatter plot and best represents the data, then it is called a best fit line.

Best fit line minimizes the squared distance of each point. Some points of the scatter plot lie above and below the best fit line.

When determining slope, data points do not usually fall within a straight line, so you need to draw a best fit line, with as many points above and below the line as possible.

Therefore the correct option is 3.
