Two versions of sample variance plots, Sv-plot1 and Sv-plot2, will be provided illustrating
the squared deviations from sample variance. Besides indicating the contribution of squared
deviations for the sample variability, these plots are capable of detecting characteristics of the
distribution such as symmetry, skewness and outliers. A remarkable graphical method based on
Sv-plot2 can determine the decision on testing hypotheses over one or two population means.
In sum, Sv-plots will be appealing visualization tools. Complete description of this methodology
can be found in the article, Wijesuriya (2020)
