What is the range? To find the range you take the biggest number subtracted by the smallest number. So 580-28=552 Range=552
What is the median? To find the median you order the numbers least to greatest and cross off the numbers left to right until you get the median aka middle number. So the median is 130
What is the upper quartile? So the median was 130 so that is the middle quartile, and the numbers above that 187,192,228,301,580 are the upper numbers so find the middle two numbers of those numbers which is 228 and 301 so you add them and divide by 2 and get 264.5 which is the upper quartile
What is the mean? You add all the numbers up and divide by the number of numbers for the mean. So all numbers added up is 2056 then divide by the amount of numbers which is 12, so 2056/12 is 171.3
