Unit 5: Statistic (Chapter 9 and 14)

In unit 5, I learn about statistic or specifically mean, median, mode and range. Also some types of table and how to make it, how to find mean, median, mode and range in the easier way in different tables or graphs.

So, for the first exercise is about mean, median, mode and range. 

Mean:

Mean is the average of all the number, by adding all the number than divided by how many numbers are there. Example the exercise below:

Find the mean of the number below:

63, 27, 19, 5, 47, 21

First just add all the number, or just follow the formula below;

So, if you follow the formula above, this is what will it look like if we put number in it

Than just solve it, first sum all the number in the numerator, than divided with the denominator.

To find a median, Example: 

Find the median of the number below:

4, 3, 7, 5, 1, 8, 3, 3, 7, 8, 3, and 6

First, arrange the number from the smallest to the
