Spss work and analysis - Coursework Example

The complete data is fed through MS Excel and converted to SPSS 16.0. Suitable tables are presented depicting the influence of each variable on unemployment. Regression Analysis: The regression is measure of functional relationship between a dependent variable and one or more independent variable(s). Here in this study, we consider the unemployment as dependent variable and the other variables such as real GDP, Net Export, investment and consumption as independent variables individually since the unemployment depends on all the other influencing and independent variables.

The data is analyzed through SPSS 16.0 package and the procedure adopted is linear regression with all the independent variables taken individually. The real values are itself considered instead of log or ln of the variables since they showed more significant correlations better than that of log or ln of the variables and also many values are missing for log or ln of the variable Net Export since the original values are negative. The data is secondary data collected through internet from the year 1995 to year 2010 for 16 years for each quarter (totally 64 values).
