the math test on the mean, median, and mode I was told was quite simple. There should be 3 or 4 questions for each mean, mode and median and 2 questions that involve all of them. 


Measures of central Tendency

3 numbers used to describe the center of a set of data are the mean, medium and mode.


Mean   -also known as average

            -calculate by adding the numbers and dividing by the # of numbers added


Median -the middle number when the numbers are arranged in order

            -if there are 2 middle numbers, the median is the mean of both numbers


Mode   -the number that occurs most often 

            -a set of data can have 1 mode, more then 1 mode, or no mode
