c) The distribution for a quantitative variable
A dot plot is a graphical representation that is used to display the distribution of a quantitative variable. It shows the frequency or count of each data point by placing a dot above the number line at the corresponding value. By using a dot plot, we can visualize the distribution of the data, including the shape, center, and spread.
The mean, median, and mode (option a) are measures of central tendency and are typically represented using other types of graphs and measures. The general shape of a distribution for a nominal qualitative variable (option b) is better represented using bar charts or pie charts. The interquartile range (option d) is a measure of spread and can be displayed using box plots or range bars.
