Definition of LEVEL OF SIGNIFICANCE. : the probability of rejecting the null hypothesis in a statistical test when it is true âcalled also significance level.
The significance level, also denoted as alpha or Î±, is the probability of rejecting the null hypothesis when it is true. For example, a significance level of 0.05 indicates a 5% risk of concluding that a difference exists when there is no actual difference.he P value of 0.03112 is statistically significant at an alpha level of 0.05, but not at the 0.01 level. If we stick to a significance level of 0.05, we can conclude that the average energy cost for the population is greater than 260.
