A scatter plot is a diagram where each value in the data set is represented by a dot.

A scatter diagram is primarily used when you want to determine if a pair of numerical data points have a cause-and-effect relationship with each other. A scatter diagram is effective at showing a relationship because it does a good job of showing the range of data points at any section.

The pattern of the scatter describes the relationship. To obtain Best-fit or trend lines should:

  • Follow the trend of the data
  • Join as many points as possible
  • Leave an equal number of unconnected points on either side.
Scatter charts show numeric coordinates along the horizontal (X) and vertical (Y) axes.
