Derrik B. (Bonus)- In section 1-1 we talked about the different ways of method sampling. There are four different ways: 1- Random Sampling: Is when all samples have the same equal chance of being chosen. 2- Cluster Sampling: Is when particular parts of the population are chosen from. 3-Convience(Lazy) Sampling: Is when things are chosen as they are readily avaliable. 4- Systematic Sampling: Is when there is a particular order or pattern being used to sample from.

Cassi K. Chris P. - In section 1-2, we learned how mean, median, mode, and range can be used to measure number sets. Mean is adding the numbers up together and dividing by how many numbers were added up to find the **average.** Median is the **middle number** or the closest measurement to a middle number. Mode would be the number that appears the most within the number set. Range is the distance between highest and lowest numbers. This can be done with A TI-81/83 calculator, or by hand.
