Question

A raw data consisting of 15 observation are arranged in ascending order, then which of the following observation represents median of the data

Answer 1

$\underline { \blue{ Median :}}$

Median is a measure of central tendency which gives the value of the middle - most observation in the data.

/* Recall that for finding the median of ungrouped

data , we first arrange the data values of the observations in ascending order.

$If \: number \: of \: observations = n$

• $If \: n \: is \: Odd , \: the \\</li></ul><p> median \: is \: the \: \big(\frac{n+1}{2}\big)^{th} \\observation\:and$
  • $If \: n \:is \: even \: then \: the \:median \\will\: be \: the \: average \: of \: the \\\big(\frac{n}{2}\big) \:and \: \big( \frac{n}{2} + 1\big)^{th} \\observations$
  • $Here , n = 15 \: \pink { ( Odd )}$

  $Median = \big(\frac{15+1}{2}\big)^{th} \:observation \\ = \big(\frac{16}{2}\big)^{th}\: observation\\= 8^{th} \:observation$

  Therefore.,

  $\red {Median}\green { = 8^{th} \:observation}$
