Question

find the median ungrouped data 715,724,725,710,729,745,694,699,6696,712,734,728,716,705,719​

Answer 1

Given the data is :- 715 , 724 , 725 , 710 , 729 , 745 , 694 , 699 , 696 , 712 , 734 , 728 , 716 , 705, 719​ .

1st step - arrange them in ascending order

694, 696, 699, 705, 710, 712, 715, 716, 719, 724, 725, 728, 729, 734, 745

2nd step - count no of values in the data = 15

3rd step - since N = 15, Median = [(N+1)/2] th term {since N is odd}

                                                      = 16/2 th term

                                                      = 8 th term

                                                      = 716

Therefore , Median of the data is 716.
