Quartiles for June:
Quartiles for July:
Quartiles for August:
Given information:
The given graph is shown below:
  
Explanation:
Consider the given information.
Make the table by using the graph.
June | 84 | 84 | 85 | 82 | 83 |
July | 85 | 86 | 87 | 84 | 85 |
August | 86 | 86 | 87 | 84 | 85 |
Since the total number of data set is 5 which is odd number so median is the exactly middle value.
Find Quartiles for June:
Sorted the data as shown:
82, 83, 84, 84, 85
Thus, median is 84.
First quartile
