Which TQM tool is most appropriate for displaying the number of students in each business discipline?

• A. Cause-and-effect diagram.
• B. Scatter diagram.
• C. Histogram.
• D. Flowchart.

Answer: (C)

The histogram is the most appropriate Total Quality Management (TQM) tool for displaying the number of students in each business discipline because it visually represents numerical data through bars, which reflect the frequency of observations in various categories. In this case, each discipline can be treated as a category, and the corresponding number of students in each discipline can be plotted on the vertical axis.

Histograms allow for easy comparison of different categories by providing a clear and immediate visual representation of how many students are enrolled in each discipline. This helps stakeholders quickly grasp the distribution of students across different fields of study, facilitating better decision-making regarding resource allocation, course offerings, and understanding trends in student preferences.

Other tools, like the cause-and-effect diagram, are used for identifying root causes of problems; scatter diagrams are used to show relationships between two variables; and flowcharts are designed for mapping processes. None of these tools are specifically suited for showcasing the distribution of discrete, countable data like the number of students in various disciplines.
