does anyone know mean , median ,mode , range?

OpenStudy (sandra):

I know most of them =)

OpenStudy (sandra):

mean is the sum of all of the numbers in a sample divided by the number of samples

OpenStudy (anonymous):

okkkkkk

OpenStudy (sandra):

median is the middle value if you lay all the numbers out in order of increasing value

OpenStudy (sandra):

mode is the most common number in the series of numbers

OpenStudy (sandra):

and range is expressed in terms of lowest number - highest number

OpenStudy (sandra):

so for example: 1, 2, 2, 3, 4

OpenStudy (sandra):

the range is 1-4

OpenStudy (anonymous):

thanks

OpenStudy (sandra):

the mean is (1+2+2+3+4)/5 = 12/5

OpenStudy (sandra):

the median is (2), since the 3rd/5 numbers is a 2

OpenStudy (sandra):

and the mode is also 2, since it's the number that appears the most times

OpenStudy (sandra):
