please answer each question with a min of one page full+ page full lengthy parghs for each question...provide examles inyour answer to please lease use refernces for each question... in text citaions original work only
1. Find a YouTube video (informative, funny, appropriate) that you can relate to this class. Comment on why you picked the video that you posted. ( syallbus below in red)
2. Find an article on correlation and answer the following questions:
What are the two variables being studied?
Did the article include a scatterplot?
Does the association appear to be linear or curved?
Would you say that the correlation is weak or strong?
Was the correlation coefficient included?
Could you make a prediction based on the data?
Please cite your article.
3. In this week’s reading from chapter 10, linear correlation, we compare two different variables to look for a positive, negative, or possibly no correlation. What two variables might you want to compare? What data can you find on the Internet about these two variables? Please include the website in which you found your data with in text ciations and proper referncing..
4. If the scatterplot of two variables yields points that make a perfect straight line (either positive or negative), they are said to have “perfect linear correlation”- the correlation coefficient is either r = 1, or r = -1. Can you think of two variables that have perfect linear correlation? Can you think of two variables that have absolutely no linear correlation at all- a linear correlation r = 0?
