All Questions Correct Answer
✅ Option d — Comparing different components
All Options:
- AContinuous data
- BNominal data
- CTime series data
- DComparing different components
Detailed Solution & Explanation
A bar chart (or bar diagram) represents data by using rectangular bars where the length of each bar is proportional to the value it represents.
- **Continuous data** is typically represented using a histogram where adjacent bars have no gaps, reflecting the continuous nature of the variable .
- **Time series data** is best represented by a line diagram (historigram) to show trends over time.
- **Nominal data** can be represented by bar charts, but the primary and most comprehensive functional objective of a bar chart in practical statistics is for **comparing different components** or categories of data visually.
Therefore, comparing different components is the correct objective of drawing a bar chart in this context.
Hence, **Option D** is the correct answer.
