Help writing hypotheses!


Less is more. Stay pure. Stay poor.
We appreciate you are interested in stats. Though, I will note that a failure to reject a null hypothesis at a set alpha is not evidence towards the null being true. As noted it could be a sample size issue. To formally test a null value, a threshold is usually stated for a margin of similarity (e.g., equality test).

I will also second that a pvalue associated with a correlation does not provide information on the correlation value, but is a frequentist statement about if you repeated the study.


Also, to the OP - constructing a scatterplot may be beneficial as well!

And how do you think the formula for correlation is related to the earlier discussion? Please answer this question.
