Question

The median of the data 5, 7, 9, 10, 11 is

Answer 1

Answer:

9

Step-by-step explanation:

(5+1)/2=3

so, the median is 3rd no data

Answer 2

CORRECT QUESTION :-

• Find the median of 5, 7, 9, 10, 11.

ANSWER :-

• Third term = 9

SOLUTION :-

◉ Arrange the data in ascending or in descending order .

➣ 5, 7, 9, 10,11

No . of terms = 5(odd)

$\implies \boxed{ \red{ \bf \: median \: = \bigg \{ \dfrac{n + 1}{2} \bigg \} } ^{ \bf \: th \: } \bf \: term}$

$\implies \bf \: \bigg \{\dfrac{5 + 1}{2} \bigg \} ^{th} term \\ \\ \implies \bf \bigg \{ \dfrac{6}{2} \bigg \} ^{th} term \\ \\ \implies \boxed{ \red{ \bf \: 3 ^{rd} \: term}}$

◉ Hence third term in the data is 9

➣ so the median is 9.

Extra INFORMATION :-

➵ Median is the value which is strictly in the middle of the list of the observation when written in ascending or descending order . it is also a measure of Central tendency .

➵ if the number of observation is even , the median is the mean or average of two middle most observation .

➵ if the number of observation is odd then median is the middle most observation .
