please mark me as brainiest. Thanks! :-)
Step-by-step explanation:
6+9+11+11+12+12+13+15+16 12 is the median
(the median is found by all numbers arranged in ascending or descending order then finding the middle number)
the mean is 6+9+11+11+12+12+13+15+16 ÷9 = 105÷9 = 11.67
(the numbers over the total amount of numbers)
e.g 1+4 to find the median it will be 1+4/2 (bcos they're 2 numbers)
