Which graphical representation is used to illustrate the distribution of sales ratios?

The histogram, or bar chart, is the most suitable graphical representation for illustrating the distribution of sales ratios because it allows for the visualization of frequency distributions of numerical data. In a histogram, data is divided into intervals (or bins), and the height of each bar reflects the number of observations that fall within each interval. This visual format makes it easy to identify patterns, such as the shape of the distribution, potential outliers, and the central tendency of the data.

When studying sales ratios, it is beneficial to see how these ratios spread out over a range, which a histogram effectively conveys. It provides insights into the frequency of different sales ratios and can help assess whether the data is normally distributed, skewed, or has multiple modes. Other options, while useful for showing different types of data, do not provide the same clarity for analyzing the distribution of sales ratios specifically. For example, a pie chart is better for showing parts of a whole, a line graph is used for trends over time, and a scatter plot is ideal for examining relationships between two quantitative variables.
