Right Click on any one of the data points and a dialog box will appear. Click ?Add Trendline?; this is what Excel calls a ?best fit line?: 16. An options window appears and to ask what type of Trend/Regression type you want.

And this then allows you when you put it on your points to see how many points are above.

A line of best fit can be roughly determined using an eyeball method by drawing a straight line on a scatter plot so that the number of points above the line and below the line is about equal (and the line passes through as many points as possible).

A line of best fit, also called a trend line or linear regression, is a straight line drawn on a graph that best represents the data on a plot. This line passes through some of the points, all of the points, or none of the points. It can be used to make predictions or to show trends in data.

When drawing the line of best fit, use a transparent ruler to see how the line fits between all the points before you draw it.

A line of best fit is a straight line that minimizes the distance between it and some data. The line of best fit is used to express a relationship in a scatter plot of different data points.

The equation of a line of best fit can be represented as y=mx+b y = m x + b , where m is the slope and b is the y-intercept. We will take a look at two examples show a scatter plot with a line of best fit to understand the concept of how to approximate the equation of a line of best fit and make predictions.
