Tableau Desktop Certified Professional — Question 72

What is a valid use case for a bar chart?

Answer options

• A. To compare measures across categories at a glance
• B. To see relationships between measures
• C. To see individual data points while also viewing associated categories
• D. To compare multiple dimensions over an extended period

Correct answer: A

Explanation

The correct answer is A because a bar chart is specifically designed for comparing values across different categories visually. Options B and C are more suited to scatter plots or line charts, which better illustrate relationships or individual points. Option D does not align with bar charts as they typically represent categorical data rather than time series data.
