Significance tests give us a formal process for using sample data to evaluate the likelihood of some claim about a population value. We calculate p-values to see. Sal walks through an example about a neurologist testing the effect of a drug to .
The P-value approach involves determining "likely" or "unlikely" by determining the probability — assuming the null hypothesis were true — of observing a more . The P value, or calculated probability, is the probability of finding the observed, or more extreme, results when the null hypothesis (H0) of a study question is true – the definition of ‘extreme’ depends on how the hypothesis is being tested. The term significance level (alpha.
