Question

A data set contains the average salary for 100 professions. alice has chosen a dotplot to display the data, and joyce has chosen a stemplot to display the data. what advantage does alice’s display have over joyce’s display? dotplots make it easier to construct large data sets, while stemplots do not. dotplots allow for data to be sorted as values are plotted, while stemplots require values to be sorted before they are entered in the plot. dotplots make it easy to determine the shape of a distribution, while stemplots do not. dotplots show the original data, while stemplots do not.

Answer 1

The advantage of using Dotplot by Alice over stemplot chosen by Joyce is that Dotplot works easier on large data sets with respect to stemplot.

Dotplot allows the data to get sorted as the values are plotted whereas stemplot requires the values to be sorted before the data must enter in the plot.

It is easy to determine the shape of the distribution, that is, symmetrical or asymmetrical while using Dotplot whereas we should not able to determine the shape of the distribution while using stemplot.

Dotplot shows the original data that is single dot represents the original number whereas stemplot does not shows the original data that is first digits of the number represents as stem and last digits represents as leaf.
