Discussion Questions

Order Description

Instructions: Answer each questions with a minimum of 500 words.

Question #1: For this weeks forum, find a news article that includes statistics. An example would be a sports story, political poll, etc. Present the article and details of the statistics. Think about how these statistics can be altered to fit the news story. Compare and contrast descriptive and inferential statistics as they apply to your news article. An example would be a political poll by CNN would have different findings than Fox News. Also discuss which type of table or graph would best explain this information and why.

Question #2: If we take the time to look and think, we can find statistics all around us. How does statistics affect your work or everyday life? For example, if you coach or train athletes, the tests you use to predict performance or determine training methods use statistics. How do these tests use statistics? Please provide details and your opinion about these items and they affect your life in regards to this weeks readings.

Question #3:
Go to the following website: https://php.delawareonline.com/news/2013/school-test-scores/

This is the site for school tests scores for the state of Delaware. You can select a district and you need to examine the test scores presented. You do not need to go into detail on each grade, but select one grade and discuss how the scores are presented. Then look at the other data available that shows test scores by race. While the overall grade is scoring say an 85% on the test, is that a true picture of the class? Why or why not? There are enough schools/districts that you cannot repeat the information provided by another student

Question #4
Read the attached article by Cohen. This is a short article on statistics. What are your views after reading the article? Was there any part of the article that helped you understand a concept better? I do not want a review of the article as everyone is reading the same article. I am looking for your thoughts and feelings on the content of the article. ( see attached docuemtn for the article listed as Cohen)

Question # 5
This week we focused on correlation.

Here are some examples of positive correlations:

1. SAT scores and college achievement—among college students, those with higher SAT scores also have higher grades

2. Happiness and helpfulness—as people’s happiness level increases, so does their helpfulness (conversely, as people’s happiness level decreases, so does their helpfulness)

Here are some examples of positive correlations:

1. Education and years in jail—people who have more years of education tend to have fewer years in jail (or phrased as people with more years in jail tend to have fewer years of education)

2. Crying and being held—among babies, those who are held more tend to cry less (or phrased as babies who are held less tend to cry more)

Think of an example of a positive and negative correlation and present each to the class. Is there any research to back up your correlation? If so, please reference the information. If you have not found anything to support your correlation, why do you feel it is accurate?
