mean

• put raw data into ascending order.

• sum of all data, devided by the number of data

• if you have an outlier it changes the mean

median

• put raw data into ascending order

• find the middle number

• its the best way to find the average of the data if there is an outlier

• if you have two middle number you have to add the two middle number and devide it by 2

mode

• put raw data into ascending order

• find the most occuring number in the data

• you can have more than one mode

• you can have no mode at all

• put raw data into ascending order

• largest data minus the smallest data

• if there is a large range check if the mean is the best way to find the average

Here is a great video representing mean,median and mode.
