Many struggle with discussions of null and alternative hypotheses. The logic behind phrasing research questions in that way can be a bit unintuitive. The logical involves what you can or cannot prove given an if-then statement, and I'll put a paragraph about that down at the bottom. In the meantime, here is a much easier way to understand what is going on:

So, after spending a long time in conversations about racism --- some time talking, but mostly listening --- I pressed those involved about on the "now what?" question. In response, I have been informed that it is my duty to go out and educate other white people. Seems odd, but there it is, and I'm gonna give it a try.

The terms Dependent and Independent can be a bit unintuitive, and many stats students struggle with them. The easier term should be "dependent", and that term is easiest to understand in an experimental context. The dependent variable is what you measure at the end of an experiment.

Many of my friends and colleagues in other parts of the world are having a really hard time wrapping their head around the continued controversy in the U.S. regarding "gay marriage." And by that, I mean, "marriage" open to same sex couples, not some new magical thing that has never existed before. Such marriages are so accepted in many other countries today, that these friends think it is simply a requisite part of being a modern nation, and see current legal controversies in the U.S. as evidence that we are morally stuck in the dark ages. Maybe we are morally stuck in the dark ages, but I don't think this controversy is as straightforward as that makes it sound. I am not advocating either position below, just trying to explain the depth of the controversy.
