Histogram Examples
Question 1: In a Park, there are 28 trees of different heights, the heights can be measured in centimeters and the range of the trees lie between 100-350 cms. Draw the Histogram for the following data,
Solution:
Since the height of the trees are lying between 100-350, we shall start by marking the heights on x-axis in groups of 50cm each and the number of trees will be mentioned on y-axis.
Therefore, if a tree has a height of 230 cm, it will lie in the rectangle 200-250.
Question 2: In the below-given table, the number of machines working in a factory for their fixed amount of time is shown. Draw the Histogram for the following data.
Solution:
The Histogram for the table mentioned above will have class intervals of 5 minutes on x-axis and the number of machines used should be on y-axis
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.
