The median is the middle number of any given set when they are in order, least to greatest. If there is an even number of values, the median is the average of the middle two.

The median is 20.

In any given set, the mode is the number that appears most often. If no number appears more frequently than any other, there is no mode. It is also possible to have more than one mode.

How can finding out that a hypothesis is not true be for scientists?

Remember that a hypothesis is a 'good' guess about a question. If a scientist comes up with a hypothesis, she will test it and then see if the testing will say 'yes'. She will then do these many times and if the answer still is 'yes' she will have it published. Many others in the same field will then review that data and they will add to the information or they may not agree.

What is the circumference of a cylinder 638mm in diameter and 1312mm in height?

d = 638mm

= 4*3.1415*319 mm

= 4008.554 mm
