This page contains a series of error bar examples.
If the amount of error has been calculated in
advance, use proc bars. If you want
ploticus to compute the mean and standard deviation, use
proc rangebar with the meanmode option.
See also the vbars prefab examples
and lines prefab examples.
Error bars to +/- one standard error were computed in advance.
Simple example where mean and standard deviation were computed by
Multiple error bars, showing increased statistical power
as sample size increases. Values computed externally, in advance.
In this example, proc rangebar computed the means and
standard deviations and displayed them as horizonal error bars.
Error bars in both horizontal and vertical directions for a scatterplot.
A more elaborate example. proc scatterplot was used to
render points, and proc bars the error bars.
The standard deviations were computed in advance.
