Construction and interpretation of Histogram
- First, mark the class intervals on X-axis and frequencies on Y-axis.
- Make sure that the scale of both axes is the same.
- The class Intervals shall always be exclusive.
- Create bars with class intervals on the x-axis and corresponding frequencies on the y-axis.
- The length of each bar reflects the Frequency when intervals are equal.
- The area of each bar is the same as its respective frequency when intervals are unequal.
Bar Graphs and Histograms
Bar graphs and Histograms: The science of collecting and analyzing data in large quantities, especially for inferring proportions in a whole form is known as Statistics. The word ‘statistics’ itself refers to numbers that are used to describe the relationships of data. Therefore, we can say that the field of applied mathematics that deals with data collection, organization, analysis, interpretation, and presentation is called statistics.
A Bar graph or a Histogram is the diagrammatic representation of data in statistics. In bar graphs or histograms, using graphs, charts, and tabular data makes it very easy to understand the concepts and relationships among data.
In this article, we have provided everything about Bar Graph and Histograms along with their properties, significance, and examples of Bar Graphs and Histograms.
