Answer: Mean=4.5
Median=5.5
Explanation:
MEAN= Add all of the numbers together then divide by 18 to get 4.5
Median=To find the median, first order your data. Then calculate the middle position based on n, the number of values in your data set. If n is an odd number, the median lies at the position (n + 1) / 2. If n is an even number, the median is the mean of the values at positions n / 2 and (n / 2) + 1. This should get you 5.5
