Answer:
Mean: 10
Median: 11
Explanation:
To find the mean you have to add up all the numbers then divide by how many there are.
E.g in 1,2,3,4 there are four numbers there so you add them all up and divide by 4
To find the median you have to sort out the numbers and put them in order of smallest to largest. Then you find the middle number.
E.g 2,3,1,4,5
You put them in order: 1,2,3,4,5
Then find the middle which is 3.
