find the median of first 15 prime numbers
 

The answer for your query is as follows:
Median is the middle term of the observation.
Arranging the first 15 primes in ascending order, we get
2, 3, 3, 7, 11, 13, 17, 19, 23, 29, 31, 37, 41, 43, 47
Therefore, mean of the above data is 19, because 19 is the middle most observation.
Hope this helps. Helpful vote pls.
