Question

Calculate the value of median: 25, 20, 15, 45, 18, 7, 10, 64, 38, 12.

19

18

20

21​

Answer 1

Answer:

19

Explanation:

firstwe arrange all the data in ascending order

that is

.

7 8 10 12 15 18 20 25 38 45 64

.

there are 10 numbers and then is even number so we apply the formula of finding median through even numbers

we take to median that is v and six number and that are 18 and 20.

we add that number 18 + 20

we get 38

now we divide 38 by 2

and we will get ans 19

hope it will help you thank you

Answer 2

Answer: The median of the given values is option (a), $19$.

Explanation:

To find the median following these steps:

Step $1$:  Arrange the given numbers from smallest to largest in numerical order.

Step $2$: If the number of numbers are even, find the two middle numbers so that there are an equal number of values to their left and right. Add the two middle ones and divide by two which gives the median and if there are an odd number of numbers then the middle number is the median.

Now on arranging the given numbers in ascending order as:

$7, 10, 12, 15, 18, 20, 25, 38, 45, 64$

As there are $10$ numbers i.e. even, then the two middle values are $18$ and $20$.

Taking their average gives the median as:

$Median = \frac{18 + 20}{2} = \frac{38}{2} = 19$
