What is the difference between the mode, median and mean?

All three are types of averages that we can calculate.1, 1, 4, 6, 8, 12, 17
We can calculate the mode by looking at which number is the most frequently occurring number, for example, with the above data, the number 1 occurs the most as it is in the list twice, whereas all the other numbers occur only once. Remember, mode sounds like most, so you're trying to find the number that is in the list most.
The median can be found by ordering the numbers in ascending order, like above and then crossing out one number from the start of the list and one number from the end of the list, until only one number remains. In this example, the remaining number would be 6. Remember, median sounds like middle, so you're trying to find the middle number.
The mean is calculated by adding all of the numbers together and dividing it by the amount of numbers, so in this example, if we add all the numbers together we get 49. If we divide 49 by the amount of numbers we have (7), we get (49/7) 7. Remember, mean is the longest one to workout because it is mean!
