Final answer:
The correct answer is: a) True. A pie chart or a bar graph would be more suitable than a line chart for showcasing the proportional size of each department within a faculty, as they better represent parts of a whole. The choice of categories in pie charts and the scale in bar graphs affect the visual presentation and interpretation of the data.
Step-by-step explanation:
The question pertains to the use of PivotCharts in visually representing data proportional to a whole, suggesting that a line chart might not be the best choice for this purpose. In context, the use of a pie chart or bar graph can be more effective in certain situations. For example, a pie chart is ideal for showing the percentage breakdown of a whole, which would be the case when displaying the size of each department within a faculty. On the other hand, a bar graph could be more appropriate if one wishes to compare exact numbers or the relative sizes of different categories clearly and with a sense of scale.
Presentation choices affect how data is perceived. For instance, when creating a pie chart, deciding the categories that make up the slices is crucial, as it can influence the visual impression of their size. Similarly, with bar graphs, adjusting the vertical axis can exaggerate or minimize the perceived differences in bar height, thus impacting the interpretation of the data. It is important to display the information clearly, using legible numbers, distinguishable colors, and an appropriate scale to ensure accurate comprehension.
