A scatter plot, also called a scattergraph or scatter diagram, is a kind of chart that shows relationships of two variables in a graph. The scatter plot or diagram shows how one variable is affected or influenced by the other variable.
It is especially useful when you are dealing with a large number of data points. The scatter plot will show the relationships in terms of strength, shape, direction, or presence of outliers.
If you are into Six Sigma, all the more reason you will find use for the scatter plot, which is in fact one of Six Sigma’s basic tools. Below is an example:
If the overall production team was able to produce 500 cars before stating the Six Sigma plan. Then with the changes in waste reduction created a change of an additional 200 cars in the same amount of time. Then the numbers would show that there was a 200-point increase. This increase could have been due to the relationship of changes that occurred with the implementation of Six Sigma.
