Question

3. What is the difference between a histogram and a bar graph, and what does that difference signify?

Answer 1

In order to get detailed information about the data collected, we arrange it graphically.

When it comes to graphical representation of the data, Histograms and Bar Graphs are widely. Since they look nearly similar, there can be a little confusion as to which to use when and where.

Some of the key differences between histograms and bar graphs that easily differentiate these two are as follows:-

1. There is no spacing between two bars in a Histogram. Whereas in Bar Graph there is proper spacing between each bar.

2.In Histograms the bars are used to show the frequencies of numerical data. On the other hand, the bars in Bar Graphs show the comparison between various categories of data.

3.The Bar Graphs show the frequency distribution of Discrete Variables whereas the Histograms show the frequencies of Continuous variables.

4. The values of Histograms show the ranges of data.Whereas, the Bar Graphs show the individual entities.

5.The bars of the bar graphs can be arranged in increasing or decreasing order but it cannot be done so in Histograms as the bars in Histograms represent the sequence of classes.

6.The size or width of a class in Bar Graphs is always the same but it may or may not be same in case of Histograms.

These are some of the differences between Histograms and Bar Graphs.
