What’s in it for you? What is Box and Whisker Plot? How to construct Box and Whisker Plot? Create a Box plot using Python
What is Box and Whisker Plot? Box and Whisker Plot in statistics shows the distribution numerical data to analyze the variability and existence of outliers in a dataset
What is Box and Whisker Plot? It is also called as Five number summary box, as it consists of the median, the quartiles (lower quartile and upper quartile), and the smallest and largest values in the distribution median Q3 Q1 max min whisker whisker
How To Construct Box And Whisker Plot? Suppose, we have sample age of 10 students at a training centre • Arrange in ascending order 15, 18, 19, 19, 20, 24, 25, 25, 27, 28 1 15, 27, 19, 18, 24, 19, 20, 25, 25, 28 • Find the median • 15, 18, 19, 19, 20, 24, 25, 25, 27, 28 2 Median = Q2 = 22
How To Construct Box And Whisker Plot? Find the medians of the two halves 15, 18, 19, 19, 20, 24, 25, 25, 27, 28 3 15, 18, 19, 19, 20 24, 25, 25, 27, 28 Lower Quartile/Q1 Upper Quartile/Q3
How To Construct Box And Whisker Plot? 15, 18, 19, 19, 20, 24, 25, 25, 27, 28 Min Max Median Q1 Q3 The five-number summary is 15, 19, 22, 25, 28 4
Graphical Representation of Box Plot • Scale and label an axis that fits the five-number summary 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 • Draw a whisker from Q1 to the min and from Q3 to the max age value
Graphical Representation of Box Plot Below is the box plot that shows the distribution of age of students at the training centre 15 16 17 18 19 20 21 22 23 24 25 26 27 28 29 Max Min Q1 Q2 Q3 25% 25% whisker whisker
