Tograph:A box and whisker plot for the set of values 120, 145, 133, 105, 117, 150, 130, 136, 128.
Given information:
The given set of values 120, 145, 133, 105, 117, 150, 130, 136, 128.
Graph:
Consider the given information.
Arrange the values in ascending order.
105, 117, 120, 128, 130, 133, 136, 145, 150
Median:
The given data has 9 observations which is odd so the median will be the middle value of the arranged data set. So, the median of the data is the data value at 5th position.
Hence the median of the data set is 130.
First quartile
The upper part will be 105, 117, 120, 128.
Thus,
  
The third
The lower part will be 133, 136, 145, 150.
Thus,
  
The required graph is shown below:
  
Interpretation:
The graph has minimum value 105 and maximum values 150.
