What is the median of 37 38 39 44 44 45 46 47 47 47 47 48 51 52 52 53 54

Line up all the numbers from decreasing to increasing number (looks like you already have that). Then, cross out the numbers on the left, than on the right, and keep crossing it out until you get to the middle. That is your median.

Here you go. The answer itself instead of instructions.
