Answer:
4.5
Step-by-step explanation:
To find the median, put the data in order from smallest to largest
1,2,2,3,4,4,5,5,8,10,10,11
The count up the number of data points
12
Divide by 2
12/2
Split the data into 2 groups, 6 in each, starting at the beginning
1,2,2,3,4,4, 5,5,8,10,10,11
Since there is an even number
Add the last number in first group and the first number in the last group and divide by 2
(4+5)/2 = 9/2 = 4.5
The median is 4.5
