Signifikansnivået, often denoted by the Greek letter alpha (α), is a fundamental concept in statistical hypothesis testing. It represents the probability of making a Type I error, which is rejecting a true null hypothesis. In simpler terms, it's the threshold below which a result is considered statistically significant.
When conducting a hypothesis test, researchers set a significance level before analyzing the data. Common choices
The p-value obtained from a statistical test is then compared to the chosen significance level. If the
The choice of significance level depends on the context of the research and the consequences of making
