Question

if tjhe mode of 10 , 11 , 12, 10, 15,14, 9,15 ,13 , 12 , x ,9 ,7 is 15 find the value of x and the median

Answer 1

since mode is defined as the most common occurence in the given data, therefore x = 15.

now for median, arrange the data in aescending order
7, 9,9,10,10,11,12,12,13,14,15,15,15

so median = n+1/2 th term
where n = 13

so
13+1/2 th term
14/2 th term
7 th term

so 7 th term = 12
therefore
median = 12

hope it helps
