Question

find mean,median,mode and range for the following numbers 13,18,13,14,13,16,14,21,13​

Answer 1

Answer: Mean=15, Median =14, Mode=13, Range=8

Step-by-step explanation:

Firstly arrange it in ascending order. It would be helpful.

13,13,13,13,14,14,16,18,21

Mode is the number which has been placed most number of times.

Here, 13 is the one which has been place most number of times.

Mode=13

Range means the difference between the highest value and lowest value

Highest value = 21

Lowest value = 13

Difference = 21 - 13 = 8

So, Range=8

Median = $\frac{No.of terms +1 }{2}$

=9 + 1 /2

=10/2

=5th value

As we wrote in the ascending order above the 5th value is 14.

Median = 14

Mean is similar to average

You have to add all the numbers given and divide it by the no.of terms given.

$\frac{13+13+13+13+14+14+16+18+21}{9}$

=15

So, Mean=15
