Highly significant p value
WebTo determine whether a result is statistically significant, a researcher calculates a p-value, which is the probability of observing an effect of the same magnitude or more extreme given that the null hypothesis is true. … WebAn observed event is considered to be statistically significant when it is highly unlikely that the event happened by random chance. More specifically, an observed event is statistically significant when its p -value falls below a certain threshold, called the level of significance.

WebP-value is a number that lies between 0 and 1. The level of significance (α) is a predefined threshold that should be set by the researcher. It is generally fixed as 0.05. The formula … The significance level, or alpha (α), is a value that the researcher sets in advance as the threshold for statistical significance. It is the maximum risk of making a false positive conclusion (Type I error) that you are willing to accept.
