Question

The difference between the highest and lowest values of the observations is called:

• A. Frequency
• B. Range
• C. Mean
• D. Class-intervals

Answer 1

The correct option is B

Range

Explanation for correct option:

(b) Range

The difference between the highest and lowest values of the observations is called range. It is given by $Range=Highestvalue-Lowestvalue$.

Explanation for Incorrect option:

(a) Frequency

The number of times a repeated event occurred as per the unit of time is known as frequency.

(c) Mean

The mean is the sum and average of the given terms. It is given by $Mean=\frac{Sumoftheterms}{Totalnumberofterms}$

(d) The class-intervals

The class interval is defined as the difference between the upper and lower class limit. It is given by $ClassInterval=upperlimit-lowerlimit$.

Therefore, option (b) range is the right answer.
