Clicking on a Bucket in the Histogram

Click the left mouse button on a bar in the histogram graph to display three sets of values for the data points represented by that bar. These values are:

• Statistics for bar - Displays the number of the bar, counting from zero to 29.

• This bar contains values ... - Displays the range of the data in the bar.

  • Any value in this bucket must be greater than or equal to the first value.

  • Any value in this bucket must be less than the second value.

• Number of values in this bar - Displays the number of values within the bar.

• Number of values in all bars - Displays the number of values within the entire dataset.

• Percent of values in this bar - Displays the values within the bar as a percentage of the entire dataset.

• Percent of values up to and including this bar - Displays a cumulative percentage. The value is the total of the selected bucket and all buckets to the left of it as a percentage of the complete data set.

These values are displayed in a Histogram Bar Statistics dialog box, as shown in Failed Cross Reference Format.
