Viewing Chart Data
To access this dialog:
-
Open the Histogram dialog, select a chart from the histogram thumbnails pane, select the Chart Data tab.
For the selected chart, the Chart Data tab tabulates the histogram bin data.
|
The Chart Data tab only contains data if the Individual Charts option was selected on the Data Selection tab. It is otherwise empty if the Compound Charts option was selected. |
Field Details:
Chart Data: this group contains a table listing the histogram data, each record represents a histogram bin on the chart:
-
DATA: the bin number.
-
LOWER/MIDDLE/UPPER: the lower, middle and upper values of the selected bin.
-
MEAN: the arithmetic mean value of samples within each bin.
-
FREQUENCY: the number of samples in each bin.
-
CUM-FREQUENCY: the cumulative number of samples up to and including the current bin.
-
%FREQUENCY: the number of samples in the current bin expressed as a percentage of the total number of samples.
-
%CUM-FREQUENCY: the cumulative number of samples up to and including the current bin expressed as a percentage of the total number of samples
-
TOTAL: the total number of samples used for the selected histogram chart.
Additional Field Details for Probability Plots:
-
CUM-PROPORTION (U): the cumulative number of samples up to the upper limit of the current bin expressed as a proportion of the total number of samples.
-
CUM-PROPORTION (M): the cumulative number of samples up to the mid point of the current bin expressed as a proportion of the total number of samples.
-
INV-NORMAL: the inverse normal distribution values corresponding to the CUM-PROPORTION (M) values.
-
PROB-LINE: the INV-NORMAL value for the corresponding standard normal distribution. This is used for plotting the model.
