Pie charts are the best choice for displaying the data for the accounting and quality control departments as they show the percentage breakdown of each leadership style. Histograms and frequency polygons are better suited for continuous rather than categorical data. Ogives show cumulative frequencies and are not needed for this simple comparison. Scatter plots are used for displaying the relationship between two continuous variables and are not relevant here.
