Multicollinearity Test Example Using SPSS

Multicollinearity Test Example Using SPSS | After the normality of the data in the regression model are met, the next step to determine whether there is similarity between the independent variables in a model it is necessary to multicollinearity test. Similarities between the independent variables will result in a very strong correlation. In addition, multicollinearity test done to avoid habits in the decision making process regarding the partial effect of independent variables on the dependent variable. Good regression model should not happen correlation between the independent variables or not happen multicollinearity. Test muticollinearity as a basis the VIF value of multicollinearity test results using SPSS.

Making process in Multicollinearity Test
  1. If the VIF value lies between 1-10, then there is no multicollinearity.
  2. If the VIF <1 or> 10, then there is multicollinearity.

Case in Multicollinearity Test

A company manager wants to know whether the regression models multicollinearity symptoms or not. Research title is "Influence of Competence and Motivation on Employee Performance". For the manager of the collected data competence, motivation and performance of employees from 40 samples. The research data as shown below.

Interpretation of Test Results Output Multicollinearity

Based on the Coefficients Output - collinearity Statistics, obtained VIF value of 1.812, meaning that the VIF value obtained is between 1 to 10, it can be concluded that there is no multicollinearity symptoms. After the test is completed multicollinearity researchers also should examine whether there was a difference of residual variance observation period to another period of observation by way of heteroscedasticity test.

  1. nice. tq. but one question, if we have control and moderating/mediating variable, should we put all in one model or differently should be tested?

  2. What is sequence of data analysis of a questionnaire in SPSS?
    1. Reliability Test
    2. Normality Test
    3. Linearity Test
    4. Multi Co linearity Test
    5. Regression Analysis
    is this sequence ok?

    Thank you
