Statistics2IntroductionThis report shows the relationship between the GDP and the port traffic. To estimate therelation, a regression analysis is conducted to determine the slope coefficient. With the helpof a regression equation, it can be determined that to what extent the traffic changesdepending upon the increase and decrease in GDP. The report also includes that to whatextent traffic will be affected by a 2% increase in GDP. Regression analysis has beenperformed in order to solve the same.Research BackgroundA GDP of a country will adversely affect its port traffic data. An increase in GDP willincrease the traffic in the country. It is very important for the government to get its facts clearabout GDP in order to determine traffic growth. A proper method is used to conduct theresearch and to find out the relationship between GDP and port traffic.Variable SelectionFollowing variables are selected to perform a regression analysis.X: it is an independent variable. As per the data, GDP is taken as an X variable.Y: it is an dependent variable and the given traffic data is considered to be Y becauseit depends upon the changes in GDPProposed MethodA method of regression analysis is used in order to find the relationship between GDP andport traffic data. A general regression equation is Y=A+Bx (Seber & Lee, 2012).Y is thedependent variable, which is to be predicted. A stands for alpha or constant. The value of Y isequal to A, when X is equal to zero. B means beta is the coefficient of X or the slope ofregression line. X is the independent variable, on which value of Y depends (Sen &Srivastava, 2012).Data AnalysisIn context to worldThe relation between GDP and traffic data of the world is identified by using regressionanalysis. A regression equation is formed on the basis of which results are derived.A general regression equation is Y=A+Bx (Seber & Lee, 2012).The below data relates to the GDP of overall world from 2005-2015 including severalcountries. Although the data for port traffic is given from 1996-2016 but for comparison,traffic data has been taken for the same period as of GDP.Data: Overall WorldYearGDPTraffic (dependent-Y)20054,68,46,562.5837,15,31,066.0320065,38,56,933.8632,30,84,816.1820076,22,87,613.3632,17,21,995.55200827,25,28,200.00
