Histogram

 

Histograms are summary graphs for a single variable. They are very useful to understand the pattern of variability in the data.

 

  • To create a histogram for a variable, click Graphs.

 

 

  • Then select Legacy Dialogues.

 

 

  • Then select Histogram.

 

 

  • A dialogue box will appear.

 

 

  • For this demonstration, we want to display a histogram for the variable Age in years. Add this variable to the Variable: text box by clicking on the variable to highlight and then clicking on the right arrow next to the Variable: text box.

 

 

  • If you would like to see the normal curve on top of the histogram, check the box underneath the Variable: text box.

 

 

  • Optional: If you would like to add Titles to your histogram, click on the Titles button to the right of the Variable: text box. Add your title, subtitle, and footnotes. Once completed, click Continue.

 

 

  • Click OK.

 

 

  • The results will display in the Output window.

 

 

  • Optional: If you would like to see age by marital status for example, you would add Age to the Variable: text box and then Marital Status to either the Rows: or Columns: text box depending on how you would like the results displayed. Click OK.
