Question

find the median of 1,2,5,7,8,13,11,10 numbers​

Answer 1

Answer:

7.5

Step-by-step explanation:

Arranging the observations in Ascending order (lower to higher) we get,

1; 2; 5; 7; 8; 10; 11; 13.

Here,

n = 8

Median for Ungrouped data for even no of observations

= average of middle two observations.

= (n/2)th observation + (n/2)+1 th observation

____________________________________

                                  2

n/2 = 4 th observation

n/2 +1 = 5 th observation.

Average of 4 th and 5 th observation.

= 7+8/2

= 15/2

= 7.5
