Histograms
It is similar to a bar graph but a histogram groups the numbers into ranges and then plot the occurrences of values in the given ranges on the graph.
Let’s consider the previous example,
Groups | Frequency |
0-10 | 2 |
10-20 | 9 |
20-30 | 22 |
30-40 | 15 |
40-50 | 8 |
50-60 | 2 |
The figure below represents this data in graphical format. The height of the bars represents the frequency of the class-interval. Notice that there is no gap between the bars. This kind of graph is called a histogram.
Grouping of Data
Grouping of Data: Data Handling or Handling of data is not just a mathematical term but is used in everyday life. When there is a requirement to record, gather, and present any type of information or data, data handling is preferably used. Statistics is a word we often hear, is not but another term for data handling. From making a bar chart of favorite candies of different students to representing a large survey done on COVID-19 cases, data handling is used and preferred.
This information in such cases is called Data. Data can be represented in both statistical ways and graphical ways. Graphical ways usually visually appealing are also easier to understand by a common person. There are many ways to represent data graphically:
- Pictograph
- Bar Graph
- Double Bar Graph
