It's 2. That's what is in the middle of the data set when you organize them in numerical order.

I thought that the median was the number in the middle, and theres 2 middle numbers so what do I do?

then there are 12 pieces of data so the position of the data is (12 +1)/2 = 6.5 the median is between the 6th and 7th score

what?......

then the median is Median = (6th score + 7th Score)/2

ooooohhh so since there are 2 middle numbers then I would have to do a number in between them like 6.5?

well after arranging the data in order.... the easy way to find the position of the median is 1. count how many scores 12 2. add 1 to the number 12 + 1= 13 3. divide the answer by 2 13/2 = 6.5 which tells you the position of the median is between the 6th and 7th scores...

so the 6th score is 1 and the 7th score is 2 so the median is median = (1 + 2)/2
