The median is B. 2.5
Step-By-Step Step-by-step explanation:
The dot plot goes by the data
1 2 2 3 3 4
those are six numbers in total!
Since 6 is an even number we'd need to find out the number in between the two numbers in the middle.
In this case that would be 2 and 3.
The number in the middle of 2 and 3 is 2.5
