Assignment #5- Pairing up

The three people I would consider working with are Sarah, Carlos and Raul.
 Sarah is a hard worker and always has a positive attitude and a smile on her face. 
 Carlos has a nice personality and is responsible so I know I could rely on him if we were to do a group project.
 Raul understands the material and is not afraid to ask questions so he would be help me understand the concepts.

Assignment #4- The Book's Website

1. my favorite part about the website was that it breaks up the chapters and has a quiz for every chapter. to take the quiz all you need to do is click on "online quizzes" which is under student resources and register. Registering was pretty easy, just write down your email and teacher's email.
 The "Statistical Applets" was another helpful application of this website because it explains the purpose of different data and how its used.
The statistics on the web was very helpful as well because it gives you external links and shows what statistics is being used in out in the real world

Assignment #3- Correlation

1. Correlation is important because it shows the relationship between two variables and how strong this relationship is. From a positive correlation we can see that both variables increase at the same time. From a negative correlation we see that one variable decreases as the other increases.
2. Correlation and regression has helped my life so far by showing me the relationship between homework and grades, they increase mutually :)
3.Correlations that have made an impact on my life are the amount of time i spend on fb v. the amount of work i get done because ice seen that the more time i spend on fb the less work i get done :/
