Blog Assignment #5- Pairing Up
1. I would consider pairing up with Alyssa, Carlos, and Sarah. Alyssa is a sweet,quiet girl that won't be unfair when it would come to a group project and I trust that she understands the material well. Carlos has a nice personality and he is trustworthy. Sarah I know is a very hard worker and I admire that; I know I can rely on her.

Assignment #4-The Books Website
3 Things of Interest i found on the book's website were:
Online Quizzes
I found these quizzes to be very helpful because it tests you and might be able to tell you how much you need to study and work on some problems. If i would have done the blog earlier in the week before the quiz on Wednesday, I could've been more prepared since most of the problems were the same as the quiz online.
To get to the online quizzes, once you log in, on the left scrollbar, click on Online Quizzes and a page with all the chapters comes up. Just click on the chapter you want to be quizzed on(:
Statistics on the Web
I really liked this feature of the website because it allows the students to have access to acceptable and probably official data/statistics which we can use for our own studies and problems to practice on. It's also more interesting since we would be working with real-life problems and it might just change our career goals and aspirations.
To reach this feature, click on Statistics on the Web that is in the left scrollbar on the main page that comes up after you log in.
TI-Inspire Support
I personally thought this feature is great, but it would be BETTER if they had a TI 83-84 Support. (:
But it is a good idea since probably most students have a TI 83-84 model. This is helpful for students that have the Inspire since I know it is more complicated to use. Maybe this can help Hrag too.(:

Assignment #3- Correlation
Correlation is important because it can leads toward a better understanding of your data. Correlation tells us how closely related our two variables are. Just because 2 variables are correlated, such that if one goes up the other does too, or if one goes up and the other goes down, it does not always mean that a change in one variable causes a change in another. Correlation can be very effective if there is a valid relationship between the variables being analyzed and we can therefore, make a mental connection between 2 variables.
Regression analysis is designed for attempting to determine the strength of a relationship between a dependent variable and multiple changing variables.
Correlation and Regression analysis has helped me in my life so far because it allows me to take observations I have seen in life and based on those, make an assumption and connection between the variables and base some of my own decisions on that.
A correlation that might make an impact on my life might be the running and back pain. If I research and find that there is a positive correlation between running and back pain, I might decide to decrease the amount I run to therefore decrease backpain, which would be reversing the effects of the corelation.
Another correlation that might make an impact on my life would be the correlation between hours of sun exposure a day and skin cancer.If the correlation between the hours of sun exposure and skin cancer is positive(the more hours in sun exposure, the more cases of skin cancer found), then I'd be in trouble. YIKES.!
