True or False. Explain

1. The median of a data set is always one of the data values.
2. The number of permutations of two items from a data set is always two times the number of combinations when talking two objects at a time from the same data set.
3. In large data sets (1,000) or more values), the mean is always one of the data values.

Interesting questions.  Lets see if I can explain one or more of them....

1.  The median might or might not be an observed value of the set.  For example, if there are an even number of items, the median will fall halfway between two of them, such that half the data is above, and half is below.  Of course, this wouldn't happen if both of those data points (nearest the median) had the same value.
