Chapter 10: Statistics & Regression Calculations
A broken line graph for the frequency distribution of sample (x)
Three types of points can be selected from circle, cross and
square.
The correlation of points between histogram and broken line plot
are shown on the right. (The broken line is displayed by connect-
ing the upper left points of the bars of the histogram, as the upper
left point of each bar represents
each class value in the histo-
gram.)
The calculator can draw both a
histogram and a broken line plot
at the same time.
Plots the variance of the
standardized normal distribution
with the statistical data (x) on
the X axis or Y axis.
If the points plot almost linearly,
it indicates that the data is of
normal distribution.
The distance between the dots is set by the Xscl.
• The Xscl can be changed between 1 and 64. Use the Window
Setting Menu to change the figure. (See page 57)
•You cannot set the frequency in the Normal probability plot. The
statistical data must be created using only one list without
splitting into the data and frequency.

The x-axis is in the range of
Xmin to Xmax.
