Example 3

medium
Explain two differences between a histogram and a bar graph.

Solution

  1. 1
    Step 1: A histogram has adjacent bars (no gaps) because it represents continuous data; a bar graph has gaps between bars because it represents categorical data.
  2. 2
    Step 2: In a histogram, the horizontal axis shows numerical intervals; in a bar graph, it shows categories that can be reordered.

Answer

Histograms: no gaps, numerical intervals, continuous data. Bar graphs: gaps, categories, categorical data.
Understanding the distinction helps us choose the right graph for our data type and interpret each correctly.

About Histogram

A histogram is a graph that groups numerical data into equal-width ranges (bins) and shows the frequency of values in each range using adjacent bars that touch. Unlike bar graphs, histograms display the distribution shape of continuous data.
