The significance level, also known as alpha, is the maximum level of error that the researcher is willing to accept. If the p-value is less than or equal to the significance level, the null hypothesis is rejected. If the null hypothesis is actually true, then rejecting it represents a Type I error, which is the risk that the researcher takes when setting the significance level. The commonly used significance level is 0.05, which means that there is a 5% chance of making a Type I error when rejecting the null hypothesis.
