In this case, you are essentially trying to find support for the null hypothesis and you are opposed to the alternative. In conclusion finding a research hypothesis requires a scientific thinking about a certain problem that is going to be answered after doing the research. In recent years free...
Errors: Type I and Type II Type I error A type I error, also known as an error of the first kind, occurs when the null hypothesis (H0) is true, but is rejected. It is asserting something that is absent, a false hit. A type I error may be compared with a so called false positi...
Hypothesis Testing Today, we are going to begin talking about the idea of hypothesis testing —how we can use statistics to show that our causal models are valid or invalid. We normally talk about two types of hypothesis: the null hypothesis and the research or alternative hypothesis. ...
Post-hoc power 不能用于: either to try to demonstrate to reviewers that the study was appropriately designed with respect to statistical power and replicability, or else to defend one's research hypothesis by explaining away a lack of observed statistically significant findings as having been due m...
Research Hypothesis:When students attend seminar classes, in addition to lectures, their performance increases. Before moving onto the second step of the hypothesis testing process, we need to take you on a brief detour to explain why you need to run hypothesis testing at all. This is explained...

The null hypothesis plays an important role in determining if the outcome is the same as expected. It enables making a decision based on data. An alternative hypothesis can help determine the change from the expected outcome. This can help in scientific research and is helpful for making st...
There are typically two types of null hypothesis statements that say one of the following: H0: There are no statistically significant differences between two or more populations. H0: There is no statistically significant effect of the treatment upon the population. In scientific papers and research,...
Testing the null hypothesis, H^BO), against alternatives, H^B1), is well established and has a proper place in scientific research. However, this testing procedure, when it is routinely applied to comparing experimental outcomes with outcomes that are quantitatively predicted from a theoretical mode...
