A significance level is a pre-set level of probability at which it is accepted that the results are due to chance or not. This level is typically set at 0.05, which means that there is a 5% probability that the results are due to chance. If the observed probability is lower than the significance level, we would reject the null hypothesis and accept the alternative hypothesis.
