One of the goals of this course is to teach you enough of the basic concepts of statistics that you can critically evaluate sources of data, claims, and published research. Statisticians collect numerical data from subgroups of populations to find out everything imaginable about the population as a whole, including whom they favor in an election, what they watch on TV, how much money they make, or what worries them. Comedians and statisticians joke that 62.38% of all statistics are made up on the spot. Because statisitcans both record and influence our behavoir it is important to distinguish between good and bad methods for collecting, presenting, and interpreting data. Upon completion of this activity, you will determine the techniques you will use to evaluate the credibility of information and statistical claims. These techniques will prove to be useful to you not only  in this course but, other courses you are taking, your future career, and in your everyday life! 

For this discussion you will be evaluating the source of the interesting claim of your choice. In Chapter 1, you learned that a claim is a statement about a property or characteristic of the population. Your claim can be one from your textbook, one that you read about on the Internet or Social Media page, or it can be one that was reported on the news.

When taking courses (or any other kind of professional development experience), it is important to think about how your new knowledge and skills can be applied to your career. Similarly, it is very important to consider what jobs this experience may help you get, and how to show off your newly acquired expertise. In this discussion, you will collaborate with peers to share observations, suggestions, and helpful tips related to job searching.

First, take some time to explore a few job postings for your ideal career. The following websites may be helpful to use:

• LinkedIn
• Indeed
• The IMA Featured Jobs webpage
• The “Search for Jobs” area of the SNHU Career page (available through the SNHU Career module)

As you explore, take note of key terms, requirements, preferences, and skills that are listed that relate to knowledge and skills covered in this course. Then, for your initial post briefly address the following questions:

• What is your ideal career, and what about it interests you?
• When exploring job postings related to your ideal career, what knowledge and skills were listed that directly relate to this course?
• What key terms or experiences would you include in your resume, cover letter, or interview to showcase your relevant knowledge and skills related to the job posting?
• Were there certain modules, topics, or skills from this course that you feel were especially relevant for your ideal career?
