Homework Sampling

Allison Brown Dr. Bird STATS 2000 1 March 2020 Homework #2: Sampling The Pew Research Center published, What Americans know about the Holocaust, in February 2020. The report outlined what Americans knew about the Holocaust in general (i.e. how Adolf Hitler rose to power and how many Jewish people died in the mentioned time period) and compared the results with survey-taker’s relgion, ethnicity, and political affiliation. According to the “methodology” section, the report’s data was compiled by a survey administered through Pew Center’s American Trends Panel. The survey that was administered were “self administered web surveys” (Pew 16). Additional from the individuals who chose to take the survey, the panel selected supplemental interviews with members from Pew’s Ipsos Knowledge Panel to take the survey. A total of 10,971 people responded to the panel out of the original 14,415 of the desired sample. For the survey, religious affiliation was later weighted due to its sway on what an individual surveyed was able to report. This data was collected through a survey. The Center for Disease Control and Prevention published, National Diabetes Statistics Report 2020: Estimates of Diabetes and its Burden on the United States , earlier this year. The study using various interactive maps and charts outlines how many individuals in the United States have Type 1 or Type 2 Diabetes, it additionally provides insight into complications that are common with both types and certain diabetic lifestyles. According to the “Detailed Methods” section the benchmark numbers mentioned in the report are from the 2010 Official Census. To find the number of individuals with the disease the researchers used the average people with diabetes, “The total number of people with diabetes is the sum of the number of those aged 18 years or older with diagnosed or undiagnosed diabetes and the number of those younger than age 18 years with diagnosed diabetes” (CDC 21). An element that is noted in this section is that the methodology is somewhat inaccurate due to assuming diabetic growth rates grow at the same rate today as they did during the last N.H.A.N.E.S. diabetic medical group report period of growth mentioned throughout the 2020 report. This data was collected through observational data. The World Bank Group published, International Debt Statistics 2020 , in January of this year. The study examines the debt that individuals across the globe obtain and how their class structure (i.e. middle, low) determines what their life with debt looks like and the trends that the countries and groups with this debt follow overtime. The data that is sent to the World Bank regularly is dependably changed from its currency to the United States Dollar. Additionally, monetary commitments, disbursements, and debt service payments are also exchanged to the USD. Total External Debt is what the study/report mainly dealt with and it was compiled by, “ … the sum of long-term external debt, short-term debt, and IMF credit. It represents the total debt owed to nonresident creditors and is repayable in both foreign and domestic currency” (World Bank 160). For short term debt, classified by having an original maturity of one year or less was also converted to USD using the same protocol. All of the data utilized in the report was drawn from World Bank groups data collected from government services and banks in the countries mentioned. Bonds, commercial loans, and stocks were all collected from each nation’s bank groups and some data was compiled with assistance from the International Monetary Fund, a group with similar goals and ambitions to the World Bank. This data was collected through observational data. These three different reports compiled by Pew Research Center, the Center for Disease Control and Prevention, and the World Bank all varied greatly on what the reports were collecting data for, therefore their sampling procedures were vastly different. For the first report from Pew regarding American knowledge of the Holocaust, those who conducted the panel had to pay attention to social factors, like religion, in order to ensure an accurate representation of the population in their survey. Unlike the first report, the following two reports from the CDC and the World Bank were both conducted with observational research. The sample sizes for each of the reports differed, the Pew report surveyed a little over ten thousand individuals, the CDC report collected data with all of the American population with type 1 or 2 diabetes which is around 29.1 million people, whereas the report from the World Bank technically considered the entire population of the planet through gathering monetary data about individuals in a country.
