To use it in a real life situation in the classroom, take all the students and line them up by their height. If you have 5 students for example
58",60",61",62",62",
add them together and divide by 5 to get the mean (average)
so 303 divided by 5 = 60.6 That is the mean
median is the number exactly in the middle of the list from lowest to highest
median = 61"
mode is the number that occurs the most often
So mode= 62"
Range is the difference between the highest and lowest number
range = 4"
