To find the mean add up all the numbers and then divide by how many numbers there are.
Median: First place all your numbers in order from least to greatest. Since you have an odd amount of numbers you will take the two middle numbers add them together then divide by two

Kara, if you have an odd amount of numbers, there will be a "middle" number
adding up the two middle numbers and dividing by 2 is done when you have an even count of numbers.
