For decades therehas been a debate in the United States of America whether having stricter gunlaws or banning firearms altogether would reduce the homicide rates connectedwith the use of firearms.
Although many left wing supporter seem to be againstpossession of firearms, the United States have the highest amount of guns ownedper person in the entire world. However, research has been limited over thepast 20 years by political pressure from the National Rifle Association (NRA) thatcut federal and private research funding related to firearms to a trickle. TheNRA argued that at least one gun study funded by the CDC was dubious and amountedto federally funded gun control advocacy.Nearly three yearsafter the mass shooting at the Sandy Hook Elementary School, President Obamaissued an executive order, lifting the bar on federal funding for research ongun violence, research on the subject has barely rebounded.That has meantthat even the most basic data, how many guns there are in the United States,where ownership is concentrated and how that is changing, how people view andvalue and use firearms, is hard to come by.For thisinvestigation, I will use the data from the official governmental site of howmany firearms were possessed in 2012 per state to the ratio of homicidesconnected to firearms. In order to see if there is a correlation or astatistical difference, the Chi squared test will be performed as well as thePearson’s correlation coefficient.
With this mathematical investigation I willtry to calculate if rate of firearm possession is correlated to the homiciderates, meaning, if it is true that more firearms cause more deaths per state. TheChi squared test will help me to analyze and determine whether or not there isa correlation between gun ownership and homicide connected to gun relateddeaths per state. Statement of Task: The purpose ofthis investigation is to determine whether there is a correlation between gunownership per state and the gun related deaths in the state. The data willprimarily be taken from non-bias official government sites that report thestatistics each year as well as various websites that update the statisticsregularly. The main purposeof this investigation is to determine whether or not there is a relationshipbetween gun ownership and firearm related homicide per state in the US. Thetype of data that will be collected and used is the statistics from theNational Rifle Association (NRA) as well as the governmental statistics of thejustice department in the US from 2012 for the firearm related homicides.
Thereason the all the data will be used from 2012 is because it is the year wherestricter gun regulations have been passed in an attempt to reduce the homiciderates relating to gun violence. Plan of Investigation: I am investigatingthe relationship between gun ownership and firearm related homicides per statesin the United States of America. With the acquired data from trustedgovernmental sources, all from the same year, a number of mathematicalprocesses will be used to analyze the data, such as a scatter plot graph,calculations of the least squared regression line and the correlationcoefficient. A chi square test will be performed to show the dependence of gunownership to firearm related homicide rates in the US. I will investigatethe correlation between guns owned per state and gun related deaths per state.The collected data will be used to find a positive, negative or zerocorrelation with the Chi square test.
This data will be analyzed and displayed,as a scattered plot graph of the data, and regression line and a correlationcoefficient will be found. For this investigation I will use the chi-squaredtest on the data to show the dependence of gun related deaths to possession of gunsby state.
