Presentation Transcript

  1. Bar Graphs

  2. A Bar Graph compares categorical variable(s) with a quantitative variable. The categorical variable goes on the X axis, and the quantitative goes on the Y axis.

  3. For example… Categorical Variable: Borough Quantitative Variable: Percent of Hispanics (Dominican)

  4. A bar graph can also compare two categorical variables with a quantitative variable: Categorical Variables: Borough Hispanic Nation of Origin Quantitative Variables: Percent of total Hispanics, by NOO

  5. Option 1: CategoricalVariable 1 together

  6. Option 1: CategoricalVariable 2 together

  7. You can/should change the scale on the Y axis based on the range of your data

  8. If you have two or more sets of quantitative data that combined equal 100%, you can also make a Segmented Bar Graph
