In the study of statistics, a statistically significant result (or one with statistical significance) in a hypothesis test is achieved when the p-value is less than the defined significance level.

## How To Set Level Of Significance

### The level of statistical significance is the level of risk that the researcher is willing to accept that the decision to reject the null hypothesis may be wrong by mis-attributing a difference to the hypothesized factor, when no difference actually exists.

- The significance level (also called Type I error rate or the level of statistical significance) refers to the probability of rejecting a null hypothesis that is in fact true. This quantity ranges from zero (0.0) to one (1.0) and is typically denoted by the Greek letter alpha (a).
- reasonable to set the level of significance as a decreasing function of sample size, as the following example shows. Suppose ( X 1 ,â€¦,X n ) is a random sample from â€¦
- In hypothesis testing, the significance level is the criterion used for rejecting the null hypothesis. The significance level is used in hypothesis testing as follows: First, the difference between the results of the experiment and the null hypothesis is determined.
- Specify the significance level and determine the corresponding critical value of the test statistic under the assumption that null hypothesis is true. Calculate the test statistic from the data. Having discussed P value and hypothesis testing, fallacies of hypothesis testing and P value are now looked into.
