Pretend that set of number that we are going to use on a data are7,9,4,2,3,1,5,6,4,4,5,7,0.Median-Line all the numbers up by numerical order from least to greatest, then pick the middle number of the set, like this.  If in this case, line up all of the numbers. 0,1,2,3,4,4,4,5,5,6,7,7,9. Cross out the numbers from the right and the left equally until you get….4! Mode is the most frequent number(s) on a data set. In this one, the mode is 4. It has more than the other numbers. Range is just a subtraction problem.. You just subtract the lowest number from the greatest number. It is 9-0 in the example, so it is 9 as the range . Mean is the most difficult one. You add up all the numbers in the data set and you divide them from how many there is. So add them up...and the total is 57. Then you divide it by 13 because there is 13 numbers in the data set. Which is 4.384615384615385. Sorry it was a difficult mean....


Mean: average of the data setMode: the number that appears the mostMedian: middle valueRange: the difference of the largest and smallest numbers
