Concept:The mode is the most frequently occurring value in a data set. A histogram displays frequency distribution using bars, and the tallest bar indicates the class interval with the highest frequency, which contains the mode.
Explanation:Step 1: Recall that the mode is the value that appears most often.
Step 2: In a histogram, each bar represents the frequency of a class interval. The bar with the maximum height corresponds to the modal class.
Step 3: Ogives (both less than and more than type) are cumulative frequency graphs used to find the median, not the mode. A frequency polygon is a line graph of frequencies but does not directly give the mode.
Step 4: Therefore, the mode of a distribution can be obtained directly from a histogram by identifying the highest bar.
Answer:A. Histogram
