What are the values of the median and the mean of this distribution? {1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6, 7}

The median( middle number), and if there is an even amount of numbers (which is what there is in this problem, there will be 2 middle numbersso u take the 2 middle numbers...add them and divide by 2 to find the median.
(3 + 3) / 2 = 6/2 = 3median is 3

the mean (average) can be found by adding up all the numbers and dividing by how many numbers there are. 55/16 = 3.4275 rounds to 3.43 <== mean

No because if you do the higher number minus the lower number you will get a positive. if you do it the other way around you will get a negative number

Yeah she/ he needs look how long that is man
