Final answer:
Stephen should use a pie chart to represent the demographic makeup of his company's employees as it can effectively show the proportion of each demographic group in the entire employee population.
Step-by-step explanation:
Stephen should use a pie chart to represent the demographic makeup of his company's employees, as it effectively illustrates parts of a whole. Pie charts are excellent for showing the percentage distribution of categorical data among different categories. In Stephen's case, each slice of the pie would represent a different demographic group within the total employee population.
For example, if Stephen wants to display the proportion of employees by age group, gender, or ethnic background, the pie chart would visually communicate how each group contributes to the entire workforce. It is essential that the pie chart is labeled clearly so that each demographic category is easily recognizable, and the percentages should be legible to facilitate understanding.
