This hypothesis makes a prediction about the effects of exercising on levels of cholesterol, and the prediction can be tested by gathering and analyzing data. Your prediction is that variable A and variable B will be related (you don't care whether it's a positive relationship. Actually, ...
Make sure, however, that you are not getting lost at this step of the thinking process: If your prediction is that there will be no difference or change, then you are trying to find support for the null hypothesis and reject H1. Directional Hypothesis While the null hypothesis is ...
As such, by taking a hypothesis testing approach, Sarah and Mike want togeneralizetheir results to a population rather than just the students in their sample. However, in order to use hypothesis testing, you need to re-state your research hypothesis as a null and alternative hypothesis. Before...
“将p-value和α对比来确定是否拒绝null”这个过程可以理解为当p-value低于预先设定的阈值时(或统计量落在α所定义的critical region时),意味着null hypothesis是true的发生的概率太低了,从而我们做出拒绝null hypothesis这个行为。注意,α既可以理解为一个阈值,也可以理解为一个概率:在统计量落在α所定义的critical ...
