Find the median of the group of numbers 2,3,3,4,5,7,8,9,10
The median of a set of ordered data values is the number such that half of the data is less than it, and half of the data is greater than it. If the group of data has an odd number of elements, then the median is the middle number.
In this case there are 9 numbers, so the 5th number in the set is the median. There are 4 numbers less than (or equal to)5(2,3,3,4) and 4 numbers greater than (or equal to )5 (7,8,9,10).
Thus 5 is the median of this set.
** If there had been an even number of elements, you would take the arithmetic mean (arithmetic average) of the two data points in the middle.
*** Note that the set must be ordered.
