Averages.

Robyn Pearce.

Hello, my name is Robyn Pearce and I will be showing you how to calculate the mode, median and mean averages of data I hope this is very helpful, and will remind you how to calculate Mode, Median and Mean averages if you ever forget

MODE

To calculate the Mode average of data, find the amount that appears the most This is the Mode average For example, the mode of these numbers; 5,6,2,2,3 is 2, as it occurs the most

To remember what Mode is, just say “Mo for Mode, Mo for Most.”

EXERCISES FOR MODE

Try these when you need a bit of practice!

Find the Mode average of:

1 89,89,45,45,45,32

2 56,23,32,23,23,23

3 134,123,123,156,156,123

MEDIAN

To calculate the Median average of a set of data, order all

of the amounts from smallest to largest Then, select the amount

in the centre (Here, the middle amount is underlined for you.)

For example, the Median amount of; 2,2,3,5,6 is 3 But, if you have another number, to make an even number, you have two numbers in the middle! To find the Median then, the

formula is 2Ma÷2=Me In other words, add the two middle amounts together and divide the result by 2 to get the Median average

EXERCISES FOR MEDIAN

Try these for practice!

Find the Median average of:

1 2,4,7,7,6

2 3,11,43,21,56,4

3 4,23,43,43,26

MEAN

This is the hardest average to find out of the 3 mentioned here It involves dividing The formula for the Mean average is: Ta÷Na=Ma In other words, the total of the amounts divided by the number of amounts you have equals the Mean average

For example, the Mean average of 2,4,3,5,7 would be 4.2,

as the total of all of the amounts is 21, and there are 5 different amounts So you would divide 21 by 5, resulting in 4.2 being the Mean average I find this easier to calculate with a calculator

This can result in getting a recurring decimal number like 4.6666666 or 3.22222222 etc., so if this happens, write 4.666r or 3.222r etc

EXERCISES FOR MEAN

Try these for practice!

Find the Mean average of:

1 4,3,67,23,2

2 34,25,14,17,46,32

3 456,231,253,687

Thank you for reading this manual on how to find averages of data I personally wish you good luck when using these

techniques Remember to check once you’ve used them!

Thank you,
