The data often follow the symmetric distribution pattern if we survey 25 males to measure their weights and heights. Most people’s data will fall within a certain amount of the typical value with few extremes in either direction. Example 2 Suppose XUZ Pvt. Ltd is a company where every 15 ...
Which of the following is an example of a bimodal histogram? a) A histogram with a single peak b) A histogram with two distinct peaks c) A histogram with a flat shape Conclusion: Histograms are invaluable tools for visualizing and interpreting numerical data. By constructing histograms, we can...
Histograms can be customized in several ways by analysts. They can change the interval between buckets. There are eight buckets in our example with an interval of 10. This could be changed to four buckets with an interval of 20. Another way to customize a histogram is to redefine the y-ax...
Let's look at an example. import pandas as pd import matplotlib.pyplot as plt # create a DataFrame with more data data = {'values': [23, 45, 30, 50, 67, 35, 47, 62, 25, 58, 42, 36, 53, 68, 32]} df = pd.DataFrame(data) # plot a customized histogram plt.hist(df['valu...
left-skewed distribution, a large number of data values occur on the right side with a fewer number of data values on the left side. A right-skewed distribution usually occurs when the data has a range boundary on the right-hand side of the histogram. For example, a boundary such as ...

To generate a histogram, the range of data values for each bar must be determined. The ranges for the bars are called bins. Most of the time, the bins are of equal size. With equal bins, the height of the bars shows the frequency of data values in each bin. For example, to create...
Example #2 Let’s take another example with 15 data points which are the salary of a company. Now we will create the bins for the above dataset. For creating the histogram chart in Excel, we will follow the same steps as in example 1. ...
