For decades there
has been a debate in the United States of America whether having stricter gun
laws or banning firearms altogether would reduce the homicide rates connected
with the use of firearms. Although many left wing supporter seem to be against
possession of firearms, the United States have the highest amount of guns owned
per person in the entire world. However, research has been limited over the
past 20 years by political pressure from the National Rifle Association (NRA) that
cut federal and private research funding related to firearms to a trickle. The
NRA argued that at least one gun study funded by the CDC was dubious and amounted
to federally funded gun control advocacy.
Nearly three years
after the mass shooting at the Sandy Hook Elementary School, President Obama
issued an executive order, lifting the bar on federal funding for research on
gun violence, research on the subject has barely rebounded.
That has meant
that 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 and
value and use firearms, is hard to come by.
investigation, I will use the data from the official governmental site of how
many firearms were possessed in 2012 per state to the ratio of homicides
connected to firearms. In order to see if there is a correlation or a
statistical difference, the Chi squared test will be performed as well as the
Pearson’s correlation coefficient. With this mathematical investigation I will
try to calculate if rate of firearm possession is correlated to the homicide
rates, meaning, if it is true that more firearms cause more deaths per state. The
Chi squared test will help me to analyze and determine whether or not there is
a correlation between gun ownership and homicide connected to gun related
deaths per state.
Statement of Task:
The purpose of
this investigation is to determine whether there is a correlation between gun
ownership per state and the gun related deaths in the state.
The data will
primarily be taken from non-bias official government sites that report the
statistics each year as well as various websites that update the statistics
The main purpose
of this investigation is to determine whether or not there is a relationship
between gun ownership and firearm related homicide per state in the US. The
type of data that will be collected and used is the statistics from the
National Rifle Association (NRA) as well as the governmental statistics of the
justice department in the US from 2012 for the firearm related homicides. The
reason the all the data will be used from 2012 is because it is the year where
stricter gun regulations have been passed in an attempt to reduce the homicide
rates relating to gun violence.
Plan of Investigation:
I am investigating
the relationship between gun ownership and firearm related homicides per states
in the United States of America. With the acquired data from trusted
governmental sources, all from the same year, a number of mathematical
processes will be used to analyze the data, such as a scatter plot graph,
calculations of the least squared regression line and the correlation
coefficient. A chi square test will be performed to show the dependence of gun
ownership to firearm related homicide rates in the US.
I will investigate
the correlation between guns owned per state and gun related deaths per state.
The collected data will be used to find a positive, negative or zero
correlation 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 correlation
coefficient will be found. For this investigation I will use the chi-squared
test on the data to show the dependence of gun related deaths to possession of guns
