Chapter 10: Statistics & Regression Calculations

3. Graphing the statistical data

Press [to access the statistical graphing mode.

The calculator can plot statistical data on up to 3 types of graph (PLOT1 to PLOT3) to check the state of distribution.

The graph types can be selected from histogram, broken line plot, normal probability plot, normal distribution plot, box plot, modified box plot, pie chart, scatter diagram and XY line. Broken line plot, normal probability plot, modified box plot, scatter diagram and XY line can use 3 different types of points — circle, cross, and square.

(HIST)

The width of the bars is set by the Xscl*.

 

The Y-axis shows the frequency.

 

* The Xscl can be changed to

 

between 1 and 64. Use the
