However, here the tags are widely used and my question precisely belongs to them. Elements of this table relevant for interpreting the results are: These results estimate that as the p-value of the ANOVA table is below the tolerable significance level, thus there is a possibility of rejecting the null hypothesis in further analysis. We have been assisting in different areas of research for over a decade. A value greater than 0.4 is taken for further analysis.
