medians, least and greatest values, where can I get help the homework makes no sense

Least and greatest values should be obvious.

1, 3, 5, 77, 1923, 9999, 1003938,

Imagine it's money. The least value is what you DON'T want to have. (1)

The greatest value is what you DO want to have ( 1003938 )

The median is different:

a) Count how many numbers there are. (There are 7 listed here)

b) Find the middle number. Since there are 7 numbers, the fourth one in is the middle number: there are three numbers on each side.

c) The middle number is the median. So the median in this example is 77 since it's the fourth number in.

In the case that you have an even amount of numbers (for example: 1, 3, 6, 8, 10, 12) The median would be the average of the two middle numbers. The two middle numbers in this case are 6 and 8. 6+8=14 Divided by 2 = 7.
