Question

For the given frequency distribution, the adjustment factor is:

C.I.	30-34	34-38	38-42
f	8	10	8

विकल्प

• \[\frac{38-34}{2}\]

• \[\frac{30+34}{2}\]

• 0

• 34 + 38

Answer 1

0

Explanation:

By formula, 

\[\text{Adjustment factor} = \frac{\text{Lower limit of one class} - \text{Upper limit of previous class}}{2}\]

The given classes (30-34, 34-38, 38-42) are already in continuous (exclusive) form, as the upper limit of each class is equal to the lower limit of the next class.

\[\Rightarrow \text{Adjustment factor} = \frac{34 - 34}{2} = \frac{0}{2} = 0.\]
