Thanks for your question.
Think of median being like a median when you drive. When you drive a car, the section the middle that you can stay on is called the median. Median = middle.
The middle number here is 5. If there are even amount of numbers, then you take the 2 middle numbers, add them, and divide by 2.
Think of mean being what did you mean by that or what did you mean to do in most cases. Mean = average of what it usually is.
To get a mean, you add up all the numbers. Then, you count the number of digits. You divide the addition by the number of digits.
