Question

Range of a set of values is $60$ and maximum value in the series is $80$. The minimum value of the series is _______.

• A. $140$
• B. $20$
• C. $70$
• D. None of the above

Answer 1

The correct option is B $20$

Range is defined as the difference between the highest(or largest ) and lowest(or smallest) observed value in a series. It is the most simple and commonly understandable measures of dispersion.

Range = 60

In the given series, H= 80 and L= x

Range => 80-x = 60

=> x = 80-60 = 20
