1. True, if you have 3 numbers (1, 2000, 2001) the median is 2000, the mean would be like 1500ish, so the mean is more informative of all the numbers, not just the one in the middle.
2. True, because it takes all the numbers into account.
3. True, since you cannot take the mean of words, but you can see how often words are present.
4. True, it's just true haha.
5. False, it could vary.
