Dot Plot

My Definition

Key Characteristics

The following are true of a dot plot:

  • The data may be numerical or categorical.

  • Dots, indicating frequencies, are placed vertically above a line labeled with categories or numerical values.

  • The dots may represent one count or more if so noted.

  • Dot plots are best for organizing a small set of data with a relatively small range.

  • A dot plot of numerical data shows the range, outliers, shape, and spread of the data.
