Statistics: Sample and Population

Discussion 1 ( make sure everything is written in your own words as it need to be submitted into turnitin)
 
To prepare: Consider an example of a sample you might find in the news media (e.g., advertisement, television news program, newspaper, web, or magazine article). Identify an example where a sample is used to represent a larger population.

(Note, you must find an article and example of a sample and population, Then answer the following question in the order please)

 
Post 2-3 paragraph 1) a brief description of the media example you found, including details about the sample. What population do you believe this sample best represents? 2) What are the advantages and disadvantages of using a sample to represent the population in your particular media example? 3) Suggest a scenario when use of a sample to represent this population might not be the best choice.

Justify your post using the Learning Resources and current literature.
 
There is an example that you must follow, please kindly look below and use as a guideline in order to complete the work. To get an A, you must follow this!. Thank you

According to Welkowitz, Cohen, and Lea (2012), an understanding of statistics is important to full understanding of others’ research and “statistical claims made in the popular media” (p.4).  Understanding samples and populations is one important component necessary to accomplishing this goal. I recently came across a study claiming that a new pill containing Garcinia Cambogia will help people lose weight. The website made claims that this pill will “burn away many pounds of fat” and that patients lost an average of 14 pounds and 6.3% BMI (“Get Garcinia Cambogia,” n.d.).  A research study was the basis of the information provided about the pill, though I believe that several liberties were taken with the interpretation of the results of that study.  

A population is the entire group of (in this case) people who belong to the group we are interested in studying, whereas a sample is the small subset of individuals whose behavior (or other variable of interest) is actually studied as part of the research (Welkowitz et al., 2012).  In the example given here, the sample would be the 30 obese patients who participated in the study. No additional information was given about the sample.  The population represented is all obese people.
 
There are several advantages to using a sample to represent the population in this study.  First, as Welkowitz and colleagues (2012) described, it is often not possible to study every member of a population.
