Cell interval in a histogram refers to the width of each bar in the histogram. It is calculated by dividing the range of the data by the number of bars. The range is the difference between the maximum and minimum values in the data set.
The cell interval is important because it determines the level of detail that is shown in the histogram. A smaller cell interval will result in a histogram with more bars, which will show more detail. A larger cell interval will result in a histogram with fewer bars, which will show less detail.
There is no one-size-fits-all answer to the question of what is the best cell interval for a histogram. The best cell interval will vary depending on the data set and the purpose of the histogram. However, there are some general guidelines that can be followed.
- If the data set is large, then a smaller cell interval can be used. This will result in a histogram with more bars, which will show more detail.
- If the data set is small, then a larger cell interval can be used. This will result in a histogram with fewer bars, which will show less detail.
- If the purpose of the histogram is to show the overall shape of the data distribution, then a larger cell interval can be used. This will result in a histogram with fewer bars, which will make it easier to see the overall shape of the distribution.
- If the purpose of the histogram is to show the details of the data distribution, then a smaller cell interval can be used. This will result in a histogram with more bars, which will make it easier to see the details of the distribution.
1. Range of the data
The range of the data is an important factor to consider when finding the cell interval for a histogram. The range is the difference between the maximum and minimum values in the data set. The cell interval should be a fraction of the range. This is because the cell interval determines the width of the bars in the histogram. If the cell interval is too large, then the bars will be too wide and the histogram will not show much detail. If the cell interval is too small, then the bars will be too narrow and the histogram will be difficult to read.
For example, consider a data set with a range of 100. If we want to create a histogram with 10 bars, then the cell interval would be 100 / 10 = 10. This means that each bar in the histogram will represent a range of 10 values.
The range of the data is an important factor to consider when finding the cell interval for a histogram because it determines the level of detail that is shown in the histogram. By considering the range of the data, you can choose the best cell interval for your data.
2. Number of bars
The number of bars in a histogram is an important factor to consider when finding the cell interval. The cell interval determines the width of the bars in the histogram, and thus the level of detail that is shown. A smaller cell interval will result in more bars, while a larger cell interval will result in fewer bars.
For example, consider a data set with a range of 100. If we want to create a histogram with 10 bars, then the cell interval would be 100 / 10 = 10. This means that each bar in the histogram will represent a range of 10 values.
If we want to create a histogram with 20 bars, then the cell interval would be 100 / 20 = 5. This means that each bar in the histogram will represent a range of 5 values.
The number of bars in a histogram is important because it affects the level of detail that is shown. A histogram with more bars will show more detail than a histogram with fewer bars. However, a histogram with more bars will also be more difficult to read.
Therefore, it is important to choose the number of bars in a histogram carefully. The number of bars should be large enough to show the desired level of detail, but not so large that the histogram is difficult to read.
3. Purpose of the histogram
The purpose of the histogram is an important factor to consider when finding the cell interval. The cell interval determines the width of the bars in the histogram, and thus the level of detail that is shown. A larger cell interval will result in fewer bars, which will make it easier to see the overall shape of the data distribution. A smaller cell interval will result in more bars, which will make it easier to see the details of the data distribution.
For example, consider a histogram of the ages of students in a school. If the purpose of the histogram is to show the overall age distribution of the students, then a larger cell interval can be used. This will result in a histogram with fewer bars, which will make it easier to see the overall shape of the distribution. For example, the cell interval could be 5 years, which would result in bars for the following age ranges: 0-4, 5-9, 10-14, and so on.
However, if the purpose of the histogram is to show the details of the age distribution of the students, then a smaller cell interval can be used. This will result in a histogram with more bars, which will make it easier to see the details of the distribution. For example, the cell interval could be 1 year, which would result in bars for the following age ranges: 0, 1, 2, 3, and so on.
It is important to choose the cell interval carefully based on the purpose of the histogram. A well-chosen cell interval will make it easy to see the desired level of detail in the data distribution.
4. Example
This example illustrates the process of finding the cell interval for a histogram. The cell interval is the width of the bars in the histogram, and it is determined by dividing the range of the data by the number of bars. In this example, the range of the data is 100 and we want to create a histogram with 10 bars, so the cell interval would be 100 / 10 = 10.

Calculating the Cell Interval
The cell interval is calculated by dividing the range of the data by the number of bars. The range of the data is the difference between the maximum and minimum values in the data set. The number of bars is the number of bars that you want to create in the histogram. -
Using the Cell Interval
Once you have calculated the cell interval, you can use it to create the histogram. The cell interval will determine the width of the bars in the histogram. The bars will be placed side-by-side, with no gaps between them. -
Interpreting the Histogram
The histogram can be used to visualize the distribution of the data. The height of each bar in the histogram represents the number of data points that fall within the corresponding cell. The histogram can be used to identify patterns and trends in the data.
This example is a simple illustration of how to find the cell interval for a histogram. In practice, you may need to consider other factors when finding the cell interval, such as the shape of the data distribution and the purpose of the histogram.
FAQs about How to Find Cell Interval in Histogram
A histogram is a graphical representation of the distribution of data. It is a type of bar graph that shows the frequency of occurrence of different values in a data set. The cell interval is the width of the bars in a histogram. It is important to choose the right cell interval because it can affect the appearance and interpretation of the histogram.
