Answer: 5
Explanation:
The median is the middle number of a group of numbers. So, to find the median, first, find out how many numbers there are. You can do this on the dot plot by counting the dots. There are 9 dots.
To find the middle number when the total is odd, you can drop the number down to an even number that will divide in half (or divide the number by two). In this case, you can drop the number to 8 and divide by two. The answer to that is 4. Because there was an odd number of dots, you should use the 4th and then the 5th numbers to determine the middle number. We also count the 5th number because the total was odd. If the total is even, use only one number as the middle number.
Since the 4th and the 5th number are lined up on the 5, that is the median number.
(If you ever have to find two numbers that are not lined up on the same number, you have to add those two numbers and divide by 2 to find the median.)
