Question

Given a continuous frequency distribution, which value must be found before actual decile calculation using the formula \[D_m=l+\frac{h}{f}\left(\frac{m\cdot n}{10}-c\right)?\]

विकल्प

• The mid-value of the decile class

• The lower boundary of the decile class

• The frequency of all classes

• The total range of data

Answer 1

The lower boundary of the decile class

Explanation:

The calculation starts with the lower boundary of the appropriate decile class; this determines the decile's location within the grouped interval.​
