What kind of frequency distribution graph shows the frequencies as bars that are separated by spaces?

• A. A bar graph
• B. A histogram
• C. A polygon
• D. All of these

Answer: (A)

Bar graphs show frequencies as separate bars with spaces between them, signaling discrete categories. That spacing emphasizes that each bar represents a distinct group. Histograms use bars that touch to indicate a continuous distribution, so there are no gaps between bars. A polygon (frequency polygon) is a line graph that connects points, not bars. Since the description specifies bars separated by spaces, the graph is best described as a bar graph.
