Statistical Plots
You can plot statistical data three ways:
■ Scatter Plot.
F or two variables, their values at each data point are
depicted by a dot in the
x-y
plane.
m
Bar Chart.
For one variable, its value at each sequential data point
is shown by a vertical bar.
■ Histogram.
For one variable, the number of times its value falls
within certain ranges—called
bins
—is depicted by a vertical bar.
Statistical plots use data stored in the reserved matrix
EDAT
variable, which plays a role for statistics analogous to
EQ
for function
plotting and solving.
