Question

If the mean, median and mode are all equal for the following set, what is the value of x

 

3,4,5,8,x

Answer 1

If x = 5, then we have the data set: 3, 4, 5, 5, 8

 

   Mode = 5 (most frequent number in the list)

 

   Mean = average = (3+4+5+5+8) / 5 = 5

 

   Median = middle value = 5
