Histogram Solved Examples
Example 1: Present the following information as a histogram:
Marks |
0-10 |
10-20 |
20-30 |
30-40 |
40-50 |
---|---|---|---|---|---|
No. of students |
30 |
70 |
40 |
28 |
55 |
Solution:
We take the Marks on the graph’s horizontal axis and, based on the first column of the data, set the scale to 1 unit = 10. We pick number of students on the vertical axis of the graph and use the second column of the table to determine the scale: 1 unit = 10. Now we’ll create the relevant histogram.
Example 2: Present the following information as a histogram:
Marks |
5-10 |
10-15 |
15-20 |
20-25 |
25-30 |
30-35 |
35-40 |
40-45 |
---|---|---|---|---|---|---|---|---|
No. of students |
10 |
15 |
18 |
26 |
35 |
42 |
54 |
62 |
Solution:
We take the Marks on the graph’s horizontal axis and, based on the first column of the data, set the scale to 1 unit = 10. We pick number of students on the vertical axis of the graph and use the second column of the table to determine the scale: 1 unit = 5. Now we’ll create the relevant histogram.
Histogram – Definition, Types, Graph, and Examples
Histogram: A histogram is a graphical representation used in statistics to show the distribution of numerical data. It looks somewhat like a bar chart, but with key differences that make it suitable for showing how data is distributed across continuous intervals or specific categories that are considered “bins”.
A histogram is similar to a bar graph. The basic difference between the two is that bar charts correlate a value with a single category or discrete variable, whereas histograms visualize frequencies for continuous variables.
In this article, we have provided every detail about Histograms, their definition, types, examples, how the histogram looks, etc.
