Question

How do you know statistical significance?

Answer 1

Knowing statistical significance :

Statistical significance is a way of mathematically proving that a certain statistic is reliable, statistical hypothesis testing is helpful to find the statistical significance

Researchers use a measure known as the $\mathrm{p}$-value to determine the statistical significance.

If the $\mathrm{p}$-value falls below the level of significance , then the results is statistically significant.

The $\mathrm{p}$-value is a function of the means and standard deviations of the data samples.

Hence, $\mathrm{p}$-value is used to know the statistical significance.
