Problem Statement
When should you use a bar chart vs line graph?
Step-by-Step Explanation
Bar charts compare categories, while line graphs show change over a continuous variable such as time.
- Identify what the question is asking. In Data Visualization, this usually means naming the known quantities, the unknown quantity, and the concept that connects them.
- Write the relevant definition, rule, or relationship before substituting numbers or manipulating symbols.
- Work one step at a time and keep units, signs, and restrictions visible.
- Check whether the answer makes sense in the original context.
Final Answer
Bar charts compare categories, while line graphs show change over a continuous variable such as time. The reliable strategy is to start from the definition, apply the correct rule carefully, and then interpret the result in plain language.
