Histogram Data Statistics
Histogram data results appear in the Histogram window in the Results pane.
There are several standard results that can be derived from the histogram
database.
The basic units of histograms are hits, and there are some results that are
expressed as hits:
• Hits — The sum of all bins (buckets) in the histogram.
• Peak — Maximum number of hits in any single bin.
Some results are expressed in the source's (vertical, horizontal or measurement)
units:
• Max — The value corresponding to the maximum bin that has any hits.
• Min — The value corresponding to the minimum bin that has any hits.
• Pk-Pk — Delta between the Max and Min.
• Mean — Mean of the histogram.
• Median — Median of the histogram.
• Mode — Mode of the histogram.
• Bin Width — The width of each bin (bucket) in the histogram.
• Std Dev — Standard deviation of the histogram.
Some results are derived from other results:
• u±1
σ — Percentage of histogram hits that lie within ±1 Std Dev of the mean.
• u±2σ — Percentage of histogram hits that lie within ±2 Std Dev of the mean.
• u±3σ — Percentage of histogram hits that lie within ±3 Std Dev of the mean.
In the Histogram results window, you can select the edit (pencil) icon to open the
Histogram dialog box.
