C) The distribution for a quantitative variable

A dot plot is a type of graphical representation used to display the distribution of a quantitative variable. It is created by placing a dot for each data point on a number line. The dots represent the frequency or count of each value in the dataset.

By using a dot plot, you can clearly visualize the distribution of the data, including the central tendency (mean, median, and mode) and the spread (interquartile range). However, a dot plot does not explicitly show the mean, median, mode, or interquartile range values. Instead, it provides a visual representation of the distribution to give insights into patterns, clusters, gaps, and outliers in the data.
