Week in Review (Mathematics) 05.11.09

In the last few weeks in math my group was mostly working on the green questions. We learnt about the mean, median, range and the mode. Mean is when you add up all of your numbers togeher and then you divide the answer by the number of numbers that you have. Median is the number in the middle. Mode is the number that is used the most. Range is also when you subtract the smallest number from the biddest number and the answer is the range.

Thanks M!
