4 IN A ROW game to practice
'Using lines of best fit' for 8th grade

Scatter graphs: use line of best fit to predict values

Scatter graphs use points to represent values that correlate the relationship between two variables. The scatter graph will indicate the degree to which the two variables are linked or related. If the variables are linked, you will be able to draw a line of best fit. The more strongly two variables are correlated, the more closely the points will follow the line of best fit.

One of the benefits of being able to draw a line of best fit is that it enables you to predict values for one of the variables that you don't have a data point for. To do so, you must first locate the independent variable on the x-axis. Draw an imaginary vertical line from that value up to the line of best fit. To get the y-axis value, draw an imaginary horizontal line from the line of best fit to the y-axis to read off the value.

It should be stressed that these predicted values will always be approximations, just as the line of best fit is usually an approximation relative to the actual data which tends to contain more variability in it than can be accommodated by a line of best fit.

In this topic you are asked to use the provided line of best fit to predict values for the dependent variable (on the y-axis) given a value for the independent variable (on the x-axis).

With our Four in a row math game you will be practicing the topic "Using lines of best fit" from 8th grade / Statistics / Two variables / Two variables. The math in this game consists of 16 questions that ask you to in each instance use the given line of best fit to predict approximate values.

Four in a row is similar to the paper game "Noughts and crosses" but we have changed it into a one-person math learning / revision game. The aim of the game is to win 4 cells in a row from a grid of 16 cells.
