Difference Of Histogram And Bar Graph. The area of each bar in a histogram. For example suppose that you noted how many students in your class had a particular hair colour. This post is a little cartoon illustrated explanation of the differences. The difference between a Bar Graph and a Histogram.
In Bar graphs the length of the bars shows the frequency but the width has no special significance but in Histograms the frequency is shown by the area of the bar. A histogram represents the frequency distribution of continuous variables. A bar graph is a pictorial representation of data that uses bars to compare different categories of data. We use histograms to present continuous data that is show the frequency of numerical data in a. A histogram is the graphical representation of data where data is grouped into continuous number ranges and each range corresponds to a vertical bar. Histograms and Bar Graphs.

Histogram In Histogram Bars are fixed On the y-axis we have numbers on the x-axis we have data which is continuous. A histogram represents the frequency distribution of continuous variables. A bar graph is a pictorial representation of data that uses bars to compare different categories of data. In Bar graphs the length of the bars shows the frequency but the width has no special significance but in Histograms the frequency is shown by the area of the bar. Bar charts have equal widths. A feature that makes a difference between histogram and bar graph is that the former can only be used in showing continuous data.
