To find the mean score, we add up all the scores and divide by the total number of games:
(211 + 183 + 162 + 151 + 202 + 195) / 6 = 1104 / 6 = 184
Therefore, Madelyn's mean score for the 6 games was 184.
The correct answer is 184.

In a typical school setting, June would be an outlier in this context because it is not within the typical range of the school year and is likely not a month where school is typically in session.
Therefore, the outlier in Ms. Thompson's data is June.

The data in the dot plot shows one outlier (at 12) that significantly differs from the rest of the data. When there is an outlier present, the mean can be heavily influenced by it and may not give an accurate representation of the typical or central value. The median, on the other hand, is not as affected by outliers and can provide a more robust measure of center.
Therefore, Zunaira should use the median to analyze her data in this case.
