Based on the data analysis, the coefficient of linear regression = 0.783 (positive). This means that job satisfaction (X) has positive influence towards employee performance (Y). From the result of T-test, the probability (significant value) of variable X toward variable Y = 0.000. It means that the probability (significant value) < 0.05. Therefore, there is significant influence from each independent variable (job satisfaction) to dependent variable (employee performance). The value of Tcount = 6.218.
