Another word for the mean is the average to find the mean add all thw numbers together then divide it by how many numbers there was.

The mode is the most common score. There maybe more than one mode in a set of data

The median is the middle score. To find the median put the numbers in a line from biggest to smallest and then we have to find the middle number if there is to of them add them together then divide by two.

The range indicates the spread of the data. To find the range it is the biggest number and smallest number. Thank you Nikeisha for this great work, it will set you up well for Y9. Mr. H
