Statistical hypothesis tests allow researchers to determine the likelihood of chance differences between groups by comparing the observed data to a null hypothesis (i.e. the idea that there is no difference between groups) and calculating a p-value, which represents the probability of getting results as extreme or more extreme than those observed if the null hypothesis were true. If the p-value is sufficiently small (typically <0.05), the researcher rejects the null hypothesis and concludes that there is likely a true difference between groups.
