Mathematics Assignment: Exploring Data Distributions (Coursework Sample) Content: EXPLORING DATA DISTRIBUTIONName of the Student:Name of the Institution:Discussion:If you were responsible for determining the unemployment rate in the united states, how would you go about it?Re: Discussionby DAVIDAn excellent topic to discuss since unemployment rate have been on the rising in the united states. First and foremost, I would like to explain unemployment so that you can be able how you can go about it. Unemployment occurs when people are without work and are actively seeking unemployment. In any economy, the labor force is the actual number of people available for work. Labor force participation rate is used by economists to measure unemployment. This is a nice starting point to kick off our discussion. Addressing the issue of unemployment one requires information about the extent and the nature of the problem. The data about how the government measures unemployment, where statistics comes from, who is regarded as employed or unemployed, who is and is no t in the labor force. These questions have been comprehensively tackled in the following websites: /cps/cps_htgm.htm, /economics/textbooks/boundless-economics-textbook/unemployment-22/measuring-unemployment-103/measuring-the-unemployment-rate-391-12488. Have a look on them.Re: DiscussionBy GraceHi David, thank you for posting.I think first and foremost the way that I can go about determining the unemployment rate is by sending out questionnaire requesting information about peoples states i.e. Employed, unemployed, Students or retired which is also done by the census Bureau after 10 years and these days retrieving information from people is easier because questionnaires can be sent via mobile phone in collaboration with service providers which is faster and more effective than sending out people with questionnaires and go to meet people physically. After gathering information about different state of people then an estimate of the unemployment is taken. i.e (Unemployed/Total Labor Force) *100.Re: DiscussionBy DavidThank you, Grace, this is a nice idea but it is limited since it does not consider many factors in question. Like the different kind of unemployment as state in the links provided thus definitely the information collected will not be very correct. Also due to increased high unemployment, many people are discouraged are no longer in the business of looking job again. So kindly consider that.Re: DiscussionBy GraceThank you David for the posting and comments. How do you go about the information not collected i.e. people who didnt answer questionnaire or people who answered incorrectly? I look forward to hearing from you.Re: DiscussionBy DavidThank you Grace for the question. Statistics is based on determining how a certain unit of people describe the characteristic of the whole population e.g. for every 10 people, 4 people are unemployed. Also data collected can be compared with the data collected by Centre Bureau of Statistics.Re: DiscussionBy JoelTha nk you, David and Grace for the insight. I think I will go for the idea of sending out questionnaire as Grace suggested the problem would be, what would the data collected mean to the government? How can the information collected be used to reduce unemployment? I look forward to hearing from youRe: DiscussionBy DavidThank you, Joel for the question. Nowadays everything is based on the information. The data collected can be used by the policy makers to determine whether measure should be taken to influence the future course of the economy or to aid those affected joblessness. Also, the reason why the government take statistics of whether anyone is unemployed, their families is affected and also the nation. Thus the nation should be taking responsibility of creating more employment to the people and this can only be done by first collecting the information about the affected subjects. Also, the website stated can help you in knowing more about what next after the data is collected1.Th e Population of United States.The current population of the United states is 324,594,222 CITATION Cen17 \l 1033 (Census.gov, 2017)based on the latest UN estimates. This population is equivalent to 4.40% of the total world population.The World population is 7,373,873,375 as at 24th February 2017 0950hrs (UTC +3) CITATION Cen17 \l 1033 (Census.gov, 2017)The population of United States in 10 years time will be 352,281,475 CITATION Geo17 \l 1033 (Geoba.se: Gazetteer - The World - Population - Top 100+ By Country (2027), 2017)2.
