If a null hypothesis is not rejected, is it true?
Can you explain to me the concept of a null hypothesis and what it means for it to not be rejected?
Sure, a null hypothesis is a statement that assumes there is no significant relationship between two variables in a certain setting. When an experiment is conducted, the null hypothesis is tested against an alternate hypothesis to see if it can be rejected. If the null hypothesis is not rejected, it means that the evidence provided by the experiment did not support the idea that the variables are related.
