Which chart type would help illustrate the relative proportions of annual turnover rate of different sub-sectors?

• A. Line Chart
• B. Histogram
• C. Boxplot
• D. Pie Chart

Answer: (D)

A Pie Chart is an effective choice for illustrating the relative proportions of annual turnover rates across different sub-sectors because it visually represents data as slices of a whole. Each slice corresponds to a sub-sector’s turnover rate and showcases how each contributes to the total turnover. This format allows viewers to quickly grasp the distribution and relative size of each sub-sector’s turnover relative to the entire dataset. By contrast, a Line Chart is more suitable for showing trends over time rather than proportions at a specific point. Histograms display the frequency distribution of continuous data but do not provide a clear breakdown of proportions among categories. Lastly, a Boxplot is designed to summarize the central tendency and variability of numeric data and is not intended to display relative proportions. Thus, for the purpose of comparing the sizes of different segments in terms of their annual turnover rates, the Pie Chart is the most appropriate selection.
