3,3,3,5,8,8,9,10,10,10,11,13,13,14,15

Q2 (main median) is in "[]"
3,3,3,5,8,8,9,[10],10,10,11,13,13,14,15

Q1 consists of ("{}" is the median but the "show solution" says it's the average of 5 and 8)
3,3,3,{5},8,8,9

this could be caused by a coding/logic error that occurs when the main median (Q2) is a repeated number.
