MCQ Questions for CBSE Class 10 Math Statistics Median Of Data With Answers

Median

For grouped data:

Median =\\(l+\\left ( \\frac{\\frac{n}{2}-cf}{f} \\right )\\times h\\)

Where l = Lower limit of the median class,

f = Frequency of the median class

c = Width of the median class,

N = The total frequency (∑f)

m = cumulative frequency of the class preceding the median class

Use formula to find

For grouped data:

Median =\\(l+\\left ( \\frac{\\frac{n}{2}-cf}{f} \\right )\\times h\\)

Where l = Lower limit of the median class,

f = Frequency of the median class

c = Width of the median class,

N = The total frequency (∑f)

m = cumulative frequency of the class preceding the median class

Find the cumulative frequency, find the median class and apply formula to find median.

Try to rember the terms in the formula.
