Presentation, communication and dissemination of vital statistics

Scatter plots

If you have two sets of data and you want to illustrate their relationship, a scatter plot is recommended. This type of chart is a powerful way to identify relationships and identify outliers. However, scatter plots are generally used more for data analysis than presentation. Scatter plots become easier to interpret if the line of best fit is drawn.
