Question

The formula to find median and explain the terms

Answer 1

Answer:

Find total frequency N= ∑fi ,Calculate 2N. Find cumulative frequency less than type which is just greater than or equal to 2N. The corresponding class is 'median ' class. Calculate the value of median by using the formula.

Median = L + [ 2N−c.

I hope this helps

Answer 2

Answer:

median

Following are the steps in the calculation of median for grouped frequency distribution

Prepare a table containing three columns

Write given class intervals in column 1 and their respective frequencies in column 2.

Write cumulative frequency less than type in column 3.

Find total frequency N= ∑fi , Calculate N/2

Find cumulative frequency less than type which is just greater than or equal to

N/2

. The corresponding class is 'median ' class

Calculate the value of median by using the formula.

Median = L + [ N/2 −c.f] h/f
