Then, you can make a bar chart, where each person is an individual bar. On the X axis you have the people, and the Y axis, you have the tuition.

4) The mean of the sample is just adding up all the numbers, and dividing by 30.
the mode is just the number that is the most common number
the median in the number in the middle.

The standard deviation is a bit more complicated.

Firstly, you have to find the mean.
then, you have to take each individual number, subtract it from the mean, and sqaure that number:

(x - mean)2.

Then you have to add up every ...
