The distance covered by an athlete in long jump practice are
6.10, 6.20, 6.18, 6.20, 6.25, 6.21, 6.15, 6.10
in metres. Find the mean and median. Why is it that there is not much difference between these?
Mean is the average value
⇒ mean = 6.17
Median is the central value of a data set.
in this question we have 8 different number, and we have to find the median of these numbers.
Let’s write them in ascending order
6.10, 6.10, 6.15, 6.18, 6.20, 6.20, 6.21, 6.25
the two central values are 
and 
, i.e., 4th and 5th numbers
which are 6.18 and 6.20
⇒ 
⇒ median = 6.19
The mean and median are approximately same because all of the data are very near to each other.
