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