Question

formula of medium ????​

Answer 1

Step-by-step explanation:

The median is the ((n + 1)/2)th item, where n is the number of values. For example, for the list {1, 2, 5, 7, 8}, we have n = 5, so the median is the ((5 + 1)/2)th item. As an example, we will calculate the sample median for the following set of observations: 1, 6, 2, 8, 7, 2.

Answer 2

CORRECT QUESTION:-

Formula of median

ANSWER:-

• The Median is the most middle value of the given grouped data if the data is grouped and when it is arranged in ascending order.

• For finding the median we require to arrange the data either in ascending order or descending order then after arranging the data we need to get the total number of observations in the data.

If the number is odd, the median is

$\frac{n + 1}{2} th \: term$

If the number is even, the median is

$\frac{( \frac{n}{2})th \: term + (\frac{n + 1}{2}) th \: term }{2}$

The median formula for grouped data is

Median =

$L_{m} + [\dfrac{\dfrac{n}{2} - F} {f_{m}}]i$

n = Total frequency

F = Cumulative frequency of class before the median class

f = Frequency of the class median

i = Class width

L = Lower boundary of the class median
