Analysis of Deviance Table - P-Values

  

The analysis of deviance table shows the amount of variation in the response data explained by the predictors and the amount of variation left unexplained.

The p-value is the most important result to consider. Use the p-value to analyze whether the regression coefficient is significantly different from zero. If the p-value is smaller than a pre-selected a-level, you can deduce that at least one coefficient is not zero. A commonly used a-level is 0.05.

Interpretation

The p-value for Length is 0.127, indicating that Length is not significantly different from zero at the 0.05 level of significance.
