About this paper

CEC 434: Second Semester Examination 2025/2026 for CEC434, Data Visualization, College of Technology, University of Buea. Exercise 1 (16 marks, 2 marks each) is eight short-answer conceptual questions: defining data visualization, naming business benefits, identifying who uses it and its purpose, describing types of data visualization, defining an outlier, explaining how data visualization works, and naming four tools for data visualization. Exercise 2 (17.5 marks) is a table-completion exercise matching seven visualization purposes (trends over time, comparing categories, part-to-whole relationships, cumulative values, distributions, relationships/correlations, hierarchies/flow) to when each chart type should be used and which chart types fall in that category. An additional 1.5 marks are allotted for presentation of the work.
