Question

In a frequency distribution, then mid value of a class intervals is $5$ and the width of the class interval is $6$ the lower limit of the class-interval is

• A. $2$
• B. $3$
• C. $4$
• D. $6$

Answer 1

The correct option is A $2$

class mark $=5$

Class width $=6$

Class interval $=(5-\frac{6}{2})$ to $(5+\frac{6}{2})$

$=\left(\frac{4}{2}\right)$ to $\frac{16}{2}$

$=2$ to $8$

$\therefore$ Lower limit $=2$
