Module 2 - Lesson 5
In this module you will review scatter plots and lines of best fit
Lesson 5 - Scatter Plots
Scatter Plots
Line of Best Fit
A line of best fit is a line that is drawn on a scatter plot to show the relationship between two sets of data. This line helps describe the overall trend or pattern in the data. This line shows the general trend in the data and can be used to estimate or predict values based on the relationship between the two variables. Imagine you have a bunch of dots scattered on a graph. The line of best fit is like trying to draw the straightest line that goes through the middle of all those dots. The line doesn't have to touch every single dot, but it should be as close as possible to the overall pattern of the dots.
A graph that shows the “general” relationship between two sets of data. For each point that is being plotted, there are two separate pieces of data. It shows how one variable is affected by another. Example of a scatter plot:
line of best fit
Lesson 5 - Scatter Plots
Positive Correlation
Negative Correlation
No Correlation
The graph increases from left to right
The graph decreases from left to right
The graph has no distinct pattern
