@marziajackson$ the mean is still 19 so A is the answer,
Finding the mean and median with an outlier is quite simple an outlier I'm I'm correct is a number way different then the rest like 1 compared to 16 so 1 is an outlier because its way different so you do mean and median the same just add the one to the data chart.
