Maths in room 12
In the senior syndicate we move to different classes for mathematics. At the moment we are learning about statistics. This week we have been learning about the following ideas:
Mean=Add the scores together and then divide them by the number of scores.
Median= To find the median you put the numbers in order then start counting from the outside and count in till you reach the middle number. If there is an even amount of numbers you will end up with 2 numbers, find the number in between those numbers for example if you had 6 and 8 the median would be seven.
Mode=The mode is the most common score. If you have 2 most common scores that means they are both modes. If all the scores are different there is no mode.
