   Nov 23, 2023 · In research, statistical significance measures the probability of the null hypothesis being true compared to the acceptable level of uncertainty regarding the true answer. We can better understand statistical significance if we break apart a study design.

   Oct 13, 2023 · The significance level (alpha) is a set probability threshold (often 0.05), while the p-value is the probability you calculate based on your study or analysis. A p-value less than or equal to your significance level (typically ≤ 0.05) is statistically significant.

   Within the social sciences, researchers often adopt a significance level of 5%. This means researchers are only willing to conclude that the results of their study are statistically significant if the probability of obtaining those results if the null hypothesis were true—known as the p value —is less than 5%.

   What is a statistical significance level?

   • Usually, the significance level is set to 0.05 or 5%. That means your results must have a 5% or lower chance of occurring under the null hypothesis to be considered statistically significant. The significance level can be lowered for a more conservative test. That means an effect has to be larger to be considered statistically significant.

   What is a significance level in hypothesis testing?

   • In hypothesis testing, researchers before running the data analysis, go through the process of specifying a significance level. So the present level is an index of the assessing evidence against the null hypothesis. Frequently applied alpha values with p < 0.10, p < 0.01 or. p < 0.05, which may change as the specifics of the study provide a reason.

   How do researchers determine statistical significance?

   • To determine statistical significance, researchers generally engage in hypothesis testing such as t-tests, chi-square tests, ANOVA and regression analysis depending on the nature of the data and research question involved. These tests yield a p-value indicating the probability of getting these outcomes assuming the null hypothesis holds.

   What is the difference between statistical significance and clinical significance?

   • Statistical significance determines if there is mathematical significance to the analysis of the results. Clinical significance means the difference is vital to the patient and the clinician. This study's statistical significance would be present as the P value was less than the prespecified alpha.

   What is the significance level (alpha)?

   • The significance level, also denoted as alpha or α, 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.
