Question

The difference of maximum and minimum values in a data is called

• A. class interval
• B. range
• C. frequency
• D. mean

Answer 1

Answer: (B)

range

Suppose that we had a data $A=\{a_1,a_2.........a_n\}$then

$Max.A=a_k,1\le k\le n$

$minA=a_j,1\le j\le n$

then for every $a_i\in A$

$a_j\le a_i\le a_k$

So,

$a_k-a_j$ is called range of A
