Mean:
The mean is the average number in a set of data. To get the mean, you have to add up all the numbers in a set of data, then divide it the sum by how many numbers there are.
Median:The median is the middle number in a set of data. To get the median, you have to arrange the data in ascending order, then cross out the numbers two by two, starting each end, going inwards until you get to the middle number.
If there is one middle number, you are done with the median. If there are two, then you have to add them up, then divide that by 2.
Mode:The mode is the middle number in a set of data. It is the number that appears most often. To get the mode, you have to arrange the numbers in ascending order (to make it easier), then look for the numbers that appear most often.
