    The Oakwood Art Center hosts a weekend art class for both kids and adults. The instructor recorded the ages of the participants to calculate the average age of the group. She wants to see if there is an outlier number that is too big or too small compared to the rest, which might affect the mean age. What is the outlier number in the data?

    Hint: An outlier is a number that is much higher or lower than the other numbers.
    Ages (years): 18, 17, 19, 21, 24, 19, 50
