Find the median of the following array.7,9,11,13,15,17,19.

The given data is :  7, 9, 11, 13, 15, 17, 19.
The above data is already arranged in ascending order.
Here, the number of observations = 7 (odd)

median = value of n + 12th observation = value of 7 + 12th observation = value of 4th observation = 13

first u need to arrange it in ascending/descending order than u need to cut the first no and the last no this u keep on doing it if the no of terms is odd it will have only one term left after cancelling the no of terms ,if the no of terms is even there will be 2 nos left after cancelling ,so u need to add both the nos and divide it by the total nos ,basically its same as finding the average .


there are 7 terms .

so first we cancel

-7 19



we have 13 is left in the middle .

so the median of the following array or group of numbers is 13 "the 4th term of the group of nos"

there is one more and many more formulaes to find the median of the grouped of data .

hope it helped u thumbs up pls!!!!11

assending order-7,9,11,13,15,17,19.

the middle value is (after cancelling on both the sides) 13.

so,therefore,the median(middle value) is 13.
