## Difference between a Bar Chart and a Histogram

A bar graph also referred to as Bar Chart or Bar Diagram is a pictorial representation of data that uses bars to compare different categories of data. It displays grouped data by way of parallel rectangular bars of equal length but varying width. The bars can be plotted vertically or horizontally. A vertical bar chart is sometimes referred to as a Column Chart. A bar graph shows comparisons among discrete categories. One axis of the chart shows the specific categories being compared and the other axis represents a measured value.

Have you ever noticed that the histogram and bar chart look quite similar, and wondered why we need two different types of chart? Well, if you closely look at them, you can understand that there are many differences between a bar graph and a histogram chart. A bar chart , which is also widely known as a column chart, is used to compare the frequency, count, total, or average of data in different categories by using vertical or horizontal bars. Discrete categories comparison is graphically visualized using a bar chart. Bars require two values, x and y, to render.

## Histogram vs Bar Graph: Must Know Differences

A bar chart is made up of bars plotted on a graph. It displays data values in thin, vertical rectangles. The height of each rectangular column is indicative of the value of its category. Bar charts can be used to show positive or negative values. The histogram is a chart representing a frequency distribution; heights of the bars represent observed frequencies. In other words, a histogram is a graphical display of data using bars of different heights. Usually, there is no space between adjacent bars.

Like dotplots , bar charts and histograms are used to compare the sizes of different groups. If you view this web page on a different browser e. A bar chart is made up of columns plotted on a graph. Here is how to read a bar chart. Like a bar chart, a histogram is made up of columns plotted on a graph. Usually, there is no space between adjacent columns.

Histogram is a type of bar chart that is used to represent statistical information by way of bars to Difference Between Histogram and Bar Chart.

## Difference Between Histogram and Bar Graph

There are two differences, one is in the type of data that is presented and the other in the way they are drawn. In bar graphs are usually used to display "categorical data", that is data that fits into categories. For example suppose that I offered to buy donuts for six people and three said they wanted chocolate covered, 2 said plain and one said with icing sugar. I would present this in a bar garph as:. Histograms on the other hand are usually used to present "continuous data", that is data that represents measured quantity where, at least in theory, the numbers can take on any value in a certain range.

A histogram is an approximate representation of the distribution of numerical data. It was first introduced by Karl Pearson. The bins are usually specified as consecutive, non-overlapping intervals of a variable. The bins intervals must be adjacent and are often but not required to be of equal size.

The fundamental difference between histogram and bar graph will help you to identify the two easily is that there are gaps between bars in a bar graph but in the histogram, the bars are adjacent to each other. After the collection and verification of data, it needs to be compiled and displayed in such a way that it highlights the essential features clearly to the users. The statistical analysis can only be performed if it is properly presented.

This is a question that is often asked.
