Answer 2

Value of first quartile for the given data is 67

Step by step calculation

value of first quartile = (n+1)/4th term

total number of values = n=11

therefore, value of first quartile = (11+1)/4

⇒12/4

⇒3rd value

First we have to arrange the given values in ascending order, which will be as follows:

65,66,67,68,69,70,81,82,83,84,85

Now third term in the arranged values is 67. So the value of the first quartile will be 67.

Value of first quartile or lower quartile tells about the spread of data from 50% of the middle values.
