Search for and identify a homeland security report that utilizes a frequency distribution to create a histogram. Explain what the report is and what the histogram represents. Annotate the variables that are being …..in the histogram and whether they are nominal, ordinal or interval/ratio variables. Provide a citation to the data report that you chose from the DHS website.
Below is a Sample Solution.

According to our text, Histogram is a “bar chart showing the distribution of values on a variable”(Brians, 2011 p. 413). Statistics plays a very important role within the Department of Homelandsecurity research. For example, I was able to locate the information on Aliens removed by criminalstatus and region and country of Nationality for Fiscal Year 2015 on the homeland security websiteprovided to us for this week’s discussion. There are many variables at play when I am looking atthischartlocatedon.Forexample, Table 9. Persons obtaining lawful Permanent Resident Status by Sex: Fiscal Year 2015has the following variables: characteristic, total, family sponsored preferences, employment-basedpreferences, immediate relatives of U.S. Citizens, diversity, refugees and asylees, and other. “The2015 Yearbook of Immigration Statisticsis a compendium of tables that provide data on foreignnationals who are granted lawful permanent residence (i.e., immigrants who receive a “greencard”), admitted as temporary nonimmigrants, granted asylum or refugee status, or are naturalized.TheYearbookalso presents data on immigration enforcement actions, including apprehensions andarrests, removals, and returns” (Class of Admission and Selected Demographic Characteristics:Fiscal Year 2015, Homeland Security). Like our book states, interval/ratio data provides us withthe most complete information of all, including categorization, rank, and distance. Interval/ratiovalues can be subjected to any arithmetic manipulation. Consequently, our measures of centraltendency and dispersion for interval/ratio data can be and should take this added info and capabilityinto account (Brians, 2011 p. 284).
