The hypothesis actually to be tested is usually given the symbol H0, and is. commonly referred to as the null hypothesis. As is explained more below, the null hypothesis is. assumed to be true unless there is strong evidence to the contrary â similar to how a person is. assumed to be innocent until proven guilty.
In the significance testing approach of Ronald Fisher, a null hypothesis is rejected if the observed data is significantly unlikely if the null hypothesis were true. In this case the null hypothesis is rejected and an alternative hypothesis is accepted in its place. If the data are consistent with the null hypothesis, then the null hypothesis is not rejected (i.e., accepted). In neither case is the null hypothesis or its alternative proven; the null hypothesis is tested with data and a decision is made based on how likely or unlikely the data is.
