Simple Error Bar Summaries for Groups of Cases

1. Select one variable and move it into the Variable field. This variable must be numeric.
2. Select one variable and move it into the Category Axis field. This variable may be numeric, string, or long string. Error bars for the variable are charted for each category on the Category Axis.
3. Select one of the alternatives from the Bars Represent group to choose whether the error bars represent Confidence interval for mean, Standard error of mean, or Standard deviation.

• If you have selected Confidence interval for mean, you can enter the confidence level into the Level text box.
• If you have selected either Standard error of mean or Standard deviation, you can choose a multiplier. Enter the value by which you want to multiply the statistic into Multiplier.

To panel the chart, move one or more categorical variables into the Panel By group. See the topic Paneled Charts for more information.
