Mode, Median, Mean and Range
Mode, Median, Mean and Range

Don't you think these words sound strange?
Don't you think these words sound strange?

I will get your mind to change


Mode, Mode, Mu, Mu, Mu, Mode, Mode
Is the number that occurs occurs the most most
Singing Mode, Mode, Mu, Mu, Mu, Mode, Mode
Is the number that occurs occurs the most most
You got 1,2,2,3,3,3,4
1,2,2,3,3,3,4, which of those numbers did I say more?
which of those numbers did I say more? 3 is the mode cause it occurs the most
Mode, Mode, Mu, Mu, Mu, Mode, Mode
Is the number that occurs occurs the most most
Singing Mode, Mode, Mu, Mu, Mu, Mode, Mode
Is the number that occurs occurs the most most
You got 1,2,2,3,3,3,4
1,2,2,3,3,3,4, which of those numbers did I say more?
which of those numbers did I say more? 3 is the mode cause it occurs the most
Now stop, lets take it to the middle. Got to find the median no time to daddle diddle
Line up all the numbers from the smallest to the big and the ones thats in the middle does a media jig
Go median, middle number, go median, middle number
Now the third ones mean, not nice but mean
Its the average number if you know what I mean
Just add up all the numbers and divide them by the number of added
Whats that, whats mean?
You add up all the numbers and divide them by the number of added
Yeah you know what I mean
You add up all the numbers and divide them by the number of added
It's the average number, mean, its the average number
1 more round and the song is done
Lets talk about range and have some fun
It's the biggest number minus the smallest number, in the group, in the group
It's the biggest number minus the smallest number , in the group, in the group

You got Mode, Median, Mean and Range
Mode, Median, Mean and Range

Don't you think these words sound strange?

Quick Explanation

Mean: The mean is the average number. Add up all the numbers and divide them by the number of added.
Median: You line up the numbers from smallest to big and the median is the number in the middle.
Mode: The mode is the number that occurs the most.
Range: The range is the biggest number minus the smallest number in the group

number

Examples
Mean:
If my numbers are 3,2,3,4, the mean is 3 because I add all the numbers = 12 then I divide by 4 because there are 3 numbers.
Median:
If my numbers are 1,2,3,4,5 the median is 3 because it is the middle number.
Mode:
If my numbers are 1,2,2,3,3,3,4 the mean is 3 because it occurs the most.
Range:
If my number are 8,2,4,3 the range is 6 because I get my largest number, 8 and minus the smallest number, 2 which equals 2.
