2. I didn't check, you need to put them in order.

3. did you add them and divide by 10? the reason I asked is that your mean has four greater, six below. That is not a usual result.

4. Looks right, I didn't do the math.

**Ms. Sue**, Monday, October 12, 2009 at 6:10pm1. The median is the number in the middle -- which in your data is between 6 and 8. Therefore that median is 7.

The median is wrong for 2. Please count again. I also get a different mean.

**p**, Monday, October 12, 2009 at 6:15pmThe median is the number for which there are as many instances that are above

that number as there are instances below it. To find the median, follow these

steps:

Step 1 Rewrite the numbers in order from smallest to largest.

Step 2 Count from both ends to find the number in the middle.

Step 3 If there are two numbers in the middle, add them together and find

their mean.
