Median
Mean, median, and mode are the three averages that locate a list. The median is the middle value after you order the data. The unit symbol is x-tilde (read 'x tilde'). For odd n, take the n+12 th value. For even n, average the n/2 th and the n+22 th values. The mode is the most frequent value.

What is it?
Mean, median, and mode are the three averages that locate a list. The median is the middle value after you order the data. The unit symbol is x-tilde (read 'x tilde'). For odd n, take the n+12 th value. For even n, average the n/2 th and the n+22 th values. The mode is the most frequent value. On a grouped table the modal class is the class with the highest frequency. Averages disagree when the list is lopsided; that disagreement is useful, not a mistake.
