To Create: The boxplot of number of visitors for 25 websites data.
The boxplot is:
There is one outlier present in the data.
Given information:
The visitors to the 25 websites are:

Concept Used:
The boxplot is created in the following steps:
Step 1: Arrange the data in ascending order.
Step 2: Compute the quartiles of the data as
Step 3: Consider the data on y-axis and plot the quartiles to obtain the box.
Step 4: Now compute the lower limit and upper limit to find the length of whiskers as follows,
Step 5: Plot the limits and connect the points with the box obtained using the quartiles.
Plot:
The boxplot created using the above steps is:
Outliers:
There is one data point lying outside the whiskers of the boxplot. So there is one outlier present in the length of the songs data.
