In a class of 28 sixth graders all but one of the students are 12 years old. Which two data measurements are the same for the students ages?
The median and the mode are the same for this set of data.
The mode is the number that is repeated more often than any other.
In this case 12 repeated 27 times.
So 12 is the mode.
The ​median is the middle value in a data set.
There are 28 numbers in the list, so the middle one will be the ( 28 + 1 ) / 2 = 29 / 2 = 14.5
If the number of data points is even, the median is the average of the two middle data points in the list.
In this case the median = ( x14 + x15 ) / 12 = ( 12 + 12 ) / 2 = 24 / 2 = 12
