The median of the numbers 4 , 15 ,19 , 21 , 6 is
(a) 19
(b) 15
(c) 15.5
(d) 17​

Answer 1

Answer:

b) 15

Step-by-step explanation:

Solution:

Numbers => 4, 15, 19, 21, 6

Let's arrange them in ascending or descending order,

4, 6, 15, 19, 21

Count of numbers, n = 5

Median = (n + 1)/2 = (5 + 1)/2 = 6/2 = 3rd term which is 15

(b)15 is the correct answer.

Extra Information:

Median is the value of the middle most item when all the items are in the order of magnitude.

Mean=> In mean we add all the observations and divide with the number of observations given.

Mode=> It is the value which occurs the most times in the list of observations.

Range=> It is the difference between the largest and smallest value from the observations given.

Answer 2

Answer:

there are 5 observations in the given data.

so, n=5 and {(n+1)/2}th observation will be the median

(5+1)/2 = 3

so, 3rd observation will be the median

data in ascending order:

4,6,15,19,21

3rd observation here is 15.

so,the median is 15.
