Question

If the observations are 2,15,21,17,4,2,11,25,17,4 then mode is

Answer 1

Answer:

Step-by-step explanation:

The mode of the observation is 17

Answer 2

Concept used :-

What is mode?

• The mode of a data set is the number that occurs most frequently in the set.

To easily find the mode :

• Put the numbers in order from least to greatest and count how many times each number occurs.

• The number that occurs the most is the mode!

Let's do it now!!!!

$\large\underline\green{\bold{ \sf \: ANSWER }}$

The observations arranged in ascending order is as

• 2, 2, 4, 4, 11, 15, 17, 17, 21, 25

The frequency distribution table is

$\begin{gathered}\boxed{\begin{array}{c|c} \bf x & \bf y \\ \frac{\qquad \qquad}{} & \frac{\qquad \qquad}{} \\ \sf 2 & \sf 2 \\ \\ \sf 4 & \sf 2\\ \\ \sf 11 & \sf 1\\ \\ \sf 15 & \sf 1\\ \\ \sf 17 & \sf 2\\ \\ \sf 21 & \sf 1\\ \\ \sf 25 & \sf 1 \end{array}} \\ \end{gathered}$

From this table,

• We conclude that observation 2, 4 and 17 occur twice.

So,

$\large\boxed{ \red{ \rm :\implies\:Mode \: of \: given \: data \: is \: 2, 4 \: and \: 17}}$
