How do you find mean meadian and range?

Median in the middle number in an ordered sequence of numbers
Ex. 2,4,6,9,10,11,14

The median is 9 because it is in the middle of the ordered series of numbers

Range in simply the largest number minus the smallest number in an ordered sequence of numbers
Ex. 14 - 2 = 12

To find the Mean add up all the numbers then divide by how many numbers there are. to find the Range take the highest number in the set and the lowest and subtract them and then the Meadian Put all the numbers in numerical order if theres an odd number mark off till you get to the middle if theres an even number of the set the two middle one you will add them both then subtract by 2.
