EMC Proven Professional – Data Science and Big Data Analytics — Question 23

If your intention is to show trends over time, which chart type is the most appropriate way to depict the data?

Answer options

• A. Line chart
• B. Bar chart
• C. Stacked bar chart
• D. Histogram

Correct answer: A

Explanation

A line chart is ideal for displaying trends over time because it connects data points with lines, making it easy to visualize changes. In contrast, bar charts and stacked bar charts are better suited for comparing quantities across categories rather than showing trends. Histograms are used for displaying frequency distributions, which does not align with the goal of showing trends over time.
