Hypothesis Testing is one of the two main methods of Inferential Statistics (statistics involving Samples). I've just uploaded a new video -- on Hypothesis Testing -- to my YouTube channel Statistics from A to Z -- Confusing Concepts Clarified.
In the last two weeks, two videos on key concepts within Hypothesis Testing, the Null Hypothesis and the Alternative Hypothesis, were uploaded to the channel. In the coming weeks, two more videos will be uploaded to complete the playlist on Hypothesis Testing. These are Reject the Null Hypothesis and Fail to Reject the Null Hypothesis.
