This package helps a user guess four things (mean, MD, scaled MSD, and
RMSD) before they get the SD. 1) The package displays the Empirical
Cumulative Distribution Function (ECDF) of the given data. The user
must choose the value of the mean by equating the areas of two colored
(blue and green) regions. The package gives feedback to improve the
choice until it is correct. Alternatively, the reader may continue with
a different guess for the center (not necessarily the mean). 2) The
user chooses the values of the Mean Deviation (MD) based on the ECDF of
the deviations by equating the areas of two newly colored (blue and
green) regions, with feedback from the package until the user guesses
correctly. 3) The user chooses the Scaled Mean Squared Deviation (MSD)
based on the ECDF of the scaled square deviations by equating the areas
of two newly colored (blue and green) regions, with feedback from the
package until the user guesses correctly. 4) The user chooses the Root
Mean Squared Deviation (RMSD) by ensuring that its intersection with
the ECDF of the deviations is at the same height as the intersection
between the scaled MSD and the ECDF of the scaled squared deviations.
Additionally, the intersection of two blue lines (the green dot) should
fall on the vertical line at the maximum deviation. 5) Finally, if the
mean is chosen correctly, only then the user can view the population SD
(the same as the RMSD) and the sample SD (sqrt(n/(n-1))*RMSD) by
clicking the respective buttons. If the mean is chosen incorrectly, the
user is asked to correct it.
