Based on mathematical statistics ,SPSS software was used to process the experimental data of springvibrator,and a regression model was established.The stiffness coefficient of spring is measured by regressioncoefficient.The error of the spring vibrator stiffness coefficient measured by this method is 0.01% comparedwith the difference method and the drawing method.The results show that SPSS software is more convenient toprocess experimental data of spring vibrator.
