Step By Step to Test Linearity Using SPSS

Step By Step to Test Linearity Using SPSS | Linearity test aims to determine the relationship between independent variables and the dependent variable is linear or not. The linearity test is a requirement in the correlation and linear regression analysis. Good research in the regression model there should be a linear relationship between the free variable and dependent variable.

Decision-making process in the Linearity Test
  1. If the value sig. Deviation from Linearity> 0.05, then the relationship between the independent variables are linearly dependent.
  2. If the value sig. Deviation from Linearity <0.05, then the relationship between independent variables with the dependent is not linear.

Example Case in Linearity Test

A company manager wants to know whether there is a linear relationship between competence with Employee Performance. For the manager of the collected data Competence and Performance of 40 samples of employees. The research data as shown below.
