How can you use mean, median, range, and mode in real life and in a classroom? (explain)

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"

because linear equations are a lot simpler than quadratics equations, and linear equations formula is a lot easier to memorize. that's why i think they're harder.
