Correct Answer Explanation
A histogram is a two-dimensional diagram.
Key Points:
- In a histogram, both width and height of rectangles are important.
- The base represents class intervals (along X-axis) and areas are proportional to class frequency.
- Unlike bar diagrams (one-dimensional), in histograms the width is as important as height.
- This is a key difference between bar diagram and histogram frequently tested in exams.
Why Other Options Are Wrong
- A. One-dimensional: Bar diagram is one-dimensional; histogram is two-dimensional.
- C. Three-dimensional: Histograms are plotted on a 2D plane.
- D. Non-dimensional: Histograms have two dimensions (width and height).
