Stats
Statistics is the science of collecting organizing and analyzing data or facts
Mean-the average of a group of numbers . "The average teacher is mean."
Example 1,2,5,2,6,2
Step1: add the numbers together
They equal 18
Step2: divide the 18 by the number of numbers in the set of data . In our example there are 6 numbers . So ,18 divide by 6
Step3: solve. 18 divide by 6 is 3
3 is the mean
Median - the middle number of of data or average of the two middle number is arranged in order. Think of the grassy area between the lanes on a highway .
Example 1,2,5,2,6
Step1: write numbers from least to greatest 1,2,2,5,6
Step: cross off the lowest number and highest number . Keep doing that until only 1 number is left

Mode - the number that occurs most often in a collection of data. If you change the last two letters in mode to st you get most. The mode is the most.
Example: 1,2,5,2,6,2 the number 2 is the mode because it appears most often.
Range - the difference between maximum and minimum values.
P
Example: 12,14,6,2,8
14 is the highest number and 2 is the lowest number . You subtract : 1
