Question

How are dotplots and stem-and-leaf displays similar? How are they different? Select all that apply. Stem-and-leaf displays group all data values having the same stem. Dotplots show all the data values but stem-and-leaf displays do not. Stem-and-leaf displays show all the data values but dotplots do not. Dotplots and stem-and-leaf displays both show all the data values. Stem-and-leaf displays group all data values having the same or different stem. Dotplots group only data values that are exactly the same. Dotplots group only data values that are in a given range.

Explanation / Answer

A Stem and Leaf Plot is a special table where each data value is split into a "stem" (the first digit or digits) and a "leaf" (usually the last digit). The "stem" is used to group the scores and each "leaf" shows the individual scores within each group.

A dot plot is a type of graphic display used to compare frequency counts within categories or groups.

Each dot represents a specific number of observations from a set of data. (Unless otherwise indicated, assume that each dot represents one observation. If a dot represents more than one observation, that should be explicitly noted on the plot)

The dots are stacked in a column over a category, so that the height of the column represents the relative or absolute frequency of observations in the category.

Therefore, the correct options are given by,
