Question

A frequency distribution can be presented graphically by a:

• A. Pie diagram
• B. Histogram
• C. Pictogram
• D. Cartogram

Hint:

For numerical frequency data, especially continuous data, always choose a histogram for the clearest representation.

Answer 1

The Correct Option is B

A histogram is a type of bar graph used to represent frequency distributions for continuous or grouped data.
In a histogram, adjacent rectangles represent class intervals, and their heights represent frequencies.
Option (A), pie diagrams, represent proportionate parts of a whole but are not specifically for continuous frequency distributions.
Option (C), pictograms, use pictures or symbols to represent quantities but are less precise.
Option (D), cartograms, are maps in which geographic regions are scaled according to a variable, not used for standard frequency distribution plots.
Thus, histograms are the correct choice for representing frequency distributions graphically.
