New Video: Alternative Hypothesis

​Last week I uploaded a video on the Null Hypothesis to the YouTube channel. This video on the Alternative Hypothesis, is the 2nd of 5 on the larger concept of Hypothesis Testing. There is some redundancy between these first two, because one can't fully discuss the Null Hypothesis without addressing the Alternative Hypothesis and vice versa. And redundancy and repetition are helpful when you're trying to understand a concept.

The Alternative Hypothesis is one of those statistics concepts on which experts disagree. Many include it as part of their recommended  approach to Hypothesis Testing. Others are strongly opposed to its use. I think it's very useful for two reasons:

1. In a 1-tailed (1-sided) test, it tells you in which direction (left or right) the tail points
2. It is also known as the "Maintained Hypothesis" or "Research Hypothesis", and it is a logical place to start  before stating the Null Hypothesis. 

See the video or the book for more on this. See also the "Videos" page on this website for more on which videos are coming soon.
