Mrs. Sakata is correcting math tests. Here are the scores for the first fourteen tests she has corrected: $62$, $65$, $93$, $51$, $55$ , $12$, $79$, $85$, $55$, $72$, $78$, $83$, $91$, and $76$. Which score does not seem to fit in this set of data? How will the outlier score affect the mean and the median of the data? Explain.
