Question

Find the mean,median and mean of following÷
3, 4, 1, 5, 6, 4, 2,4.​

Answer 1

Answer:

Mean- 29

Median-5.5

Mode-4

Answer 2

SOLUTION :

Given :

The raw data is 3, 4, 1, 5, 6, 4, 2, 4

Now,

To be found :

The Mean, Mode, Median

So,

Mean = average

\bf Mean= \frac{Sum\:\:of \:\:all\:\: numbers}{Number \:\:of \:\:observations}Mean=

Numberofobservations

Sumofallnumbers

So, \bf Mean=\frac{(3+4+1+5+6+4+2+4)}{8}Mean=

8

(3+4+1+5+6+4+2+4)

\bf Mean=\frac{29}{8}Mean=

8

29

\bf Mean = 3.62Mean=3.62

so, Mean = 3.62

Now,

Mode : The number which occur more number of times in the data.

So, from the given data 3, 4, 1, 5, 6, 4, 2, 4

4 occurs 3 times

Therefore, mode is 4

Now,

Median : The middle term.

First we have to arrange the given data in ascending and descending order.

In ascending order - , 1, 2, 3, 4, 4, 4, 5, 6

So,

median = \frac{4+4}{2} =\frac{8}{2}=4median= 2

4+4 =

2

8

=4

So, The median is 4.

Hence,

Mean = 3.62

Mode is 4

Median is 4
