Question

In a grouped frequency distribution, the formula to find median is

• A. \(1 + \frac{n}{2} - cf \div f \times h\)
• B. \(1 - \frac{n}{2} + cf \div f \times h\)
• C. \(1 + \frac{n}{2} - cf \div f \times h\)
• D. \(1 - \frac{n}{2} - cf \div f \times h\)

Hint:

To find the median, use the formula for grouped data. Ensure to use cumulative frequency and the class width for accurate results.

Answer 1

The Correct Option is A

The correct formula to find the median in a grouped frequency distribution is given by: \[ \text{Median} = 1 + \frac{n}{2} - cf \div f \times h \] Where: - \(n\) is the total number of observations - \(cf\) is the cumulative frequency before the median class - \(f\) is the frequency of the median class - \(h\) is the class width
