Calculate the mean and the median of the numbers : 2, 1, 0, 3, 1, 2, 3, 4, 3, 5
Calculate the mean and the median of the numbers : 2, 1, 0, 3, 1, 2, 3, 4, 3, 5

Solution:

Arranging the numbers in ascending order :

0, 1, 1, 2, 2, 3, 3, 3, 4, 5

Here, n = 10 which is even

Median = ½ ( n/2 th term + ((n/2)+1)th term)

= ½ (10/2 th term + ((10/2)+1)th term)

= ½ (5 th term + (5+1)th term)

= ½ (5 th term + 6th term)

= ½ (2+3)

= ½ ×5

= 2.5

Hence the median is 2.5.

Mean = sum of the observations/ number of observations

= Ʃxi/n

= (0+1+1+2+2+3+3+3+4+5)/10

= 24/10

= 2.4

Hence the mean is 2.4.
