Question

For an ungrouped data 10,15,20,25,15,x median and mode are equal.Find x and also mean for the above data

Answer 1

Median = number of terms / 2 [ in even number case ]
             = 6 / 2 
             = 3rd term
3rd term = x, 10, 15, 15, 20, 25
              = 15
So, Mode = 15
Mean = sum / total obs
          = x + 10 + 15 + 15 + 20 + 25 / 6
          = x + 45 / 6

Hope It Helps!!! ^_^
