A stemplot is an appriopriate display for which type of variables?

Question

BlackTom AI · Accepted Answer

The question asks: A stemplot is an appropriate display for which type of variables?

Option presented: 'Quantitative'

Stemplots (also called stem-and-leaf plots) are a graphical display designed to show the distribution of numerical, continuous, or discrete quantitative data. They preserve the actual data values (to some extent) and reveal shape, center, spread, and potential modes of a dataset. This makes them well-suited for quantitative variables.

If the data were qualitative or categorical (such as categories like 'red/blue/green' or 'apple/orange/banana'), a stemplot would not be appropriate because it relies on the numerical ordering and magnitude of values to form stems and leaves. Categorical data are typically summarized with bar charts, pie charts, or frequency tables instead.

Thus, considering the nature of stemplots and what they are designed to display, the given option 'Quantitative' correctly identifies the type of variables for which a stemplot is appropriate.

Note: The provided answer options are not listed beyond the single option, so a comparison with alternative types (like categorical or ordinal) cannot be shown here. In a full set of options, you would contrast 'Quantitative' with 'Qualitative' or 'Categorical' to illustrate why stemplots are not suitable for non-numeric data.
