Question

find the median of the following data 15,35,18,27,19,23,29,20,28

Answer 1

Step 1) Arrange all the numbers in ascending order

Step 2) Calculate (n+1)/2 where, n= no. of terms

Step 3) {(n+1)/2}th term is going to be median

Solution:

Step 1: 15,18,19,20,23,27,28,29,35

Step 2: (9+1)/2 = 5

Step 3; 5th term = Median

So, Median = 23

Answer 2

$\boxed{\boxed{\Large\mathbf{19}}}$

$\underline{\underline{\huge\mathfrak{ANSWER}}}$

Median of the data = Middle most term

Total Terms = 9

Hence, the total Terms are odd.

Median for odd number of terms = $\frac{n + 1}{2}$

$\textsf{where} \: \bf{n} \: \textsf{is total number of observations}$

$\large\mathsf{\Longrightarrow \frac{9 + 1}{2}}$

$\large\mathsf{\Longrightarrow \frac{\cancel{10}}{\cancel{2}}}$

$\mathsf{\Longrightarrow 5}$

$\mathbf{Hence, \: 5^{th} term \: is \: the \: median.}$

$\boxed{\mathbf{5^{th} \: Term = 19}}$

$\textbf{Hence, the median is 19 .}$
