WebApr 17, 2024 · In regard to this issue, it is worth noting that classical hypothesis tests have some unusual (and not very helpful) properties when you compare across different tests. One of their properties is that, for a symmetric test, the p-value of the two-sided test is twice as high as the p-value for the one-sided test when data is in the relevant tail. After developing your initial research hypothesis (the prediction that you want to investigate), it is important to restate it as a null (Ho) and alternate (Ha) hypothesis so that you can test it mathematically. The alternate hypothesis is usually your initial hypothesis that predicts a relationship between variables.
