P-values indicate the strength of the evidenceagainstsampling error producing the sample effect. And the significance level defines how strong the evidence must be to reject the notion that the sample effect is a mirage caused by sampling error. Therefore, you need to compare yourp-valueto the ...
Misinterpretations are both common and persistent, leading many to question whether significance tests should be used at all. While most take aim at the arbitrary declaration of p < 0.05 as a threshold for determining 'significance', others extend the critique to suggest the 'p-value' should ...
” After determining the threshold of significance (α = 0.05), the appropriate statistical test would produce a test statistic and a correspondingp-value—say,p= 0.001. Because thisp-value is less than α = 0.05, the null hypothesis would be rejected, leading to the conclusion that a true...
Statistical methods allow an estimate to be made of the probability of the observed degree of association between variables, and from this the statistical significance can be expressed, commonly in terms of the p value.

The Mind-Reading Salmon: The True Meaning of Statistical Significance ByCharles Seife If you want to convince the world that a fish can sense your emotions, only one statistical measure will suffice: thep-value. Thep-value is an all-purpose measure that scientists often use to determine whether...
The level of significance is defined as the fixed probability of wrong elimination of null hypothesis when in fact, it is true. Visit BYJU’S to learn the definition, steps and examples.

Microsoft Excel has built-in functions to perform some of the calculations needed for statistical significance tests. To perform a chi-squared test, type =CHISQ.TEST(ActualRange, ExpectedRange), where the arguments are arrays of cells. To measure a p-value, use the function =T.TEST. ...
