To Plot: The boxplot of the length of songs data.
The earlier 12 years and later 12 years data boxplot is:
Given information:
Earlier 12 Years | Later 12 Years |
143 | 136 |
120 | 124 |
120 | 179 |
139 | 131 |
124 | 180 |
144 | 137 |
131 | 156 |
132 | 202 |
148 | 191 |
163 | 197 |
140 | 230 |
177 | 190 |
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 data in ascending order is:
Earlier 12 Years | Later 12 Years |
120 | 124 |
120 | 131 |
124 | 136 |
131 | 137 |
132 | 156 |
139 | 179 |
140 | 180 |
143 | 190 |
144 | 191 |
148 | 197 |
163 | 202 |
177 | 230 |
The boxplot of earlier 12 years data is:
The boxplot of later 12 years is:
b.
To find: The data that has greater interquartile range
The data of later 12 years had greater interquartile range.
Given:
The quartiles from the boxtplot are
The quartiles from the boxtplot are
The IQR of the later 12 years data has
