Answer:
The median would be 17.
Explanation:
The first thing to do to find median is order the numbers from least to greatest. (11, 13, 15, 15, 16, 18, 18, 20, 25, 28.) Then you find the two middle numbers (16 and 18) and do 16+18/2 16+18 is 34 and 34/2 is equal to 17, getting you your answer :) I hope this helps! ^^
