Discussing hypothesis testing may sound like a complicated task. It really shoul

Discussing hypothesis testing may sound like a complicated task. It really should not be. In simple terms, the whole process is about assumptions. Analysts assume that something has validity, and they need to test whether such an assumption can be rejected. If an assumption has validity, then people can make more accurate predictions. In short, it is about assumptions and testing whether these assumptions were valid. Provide an example of the null hypothesis and a corresponding example of the alternative…

Often times there are so many variables involved in a study that it is difficult

Often times there are so many variables involved in a study that it is difficult to distinguish "causes". For example, there is the belief that "smoking causes lung cancer". I tend to believe this myself but my own mother was a chain smoker and never developed lung cancer. There are many other variables that might affect the outcome of lung cancer such as working conditions, heredity, diet, etc. It is too hard to account for every "factor" in these circumstances…

As a scholar-practitioner, it is important for you to understand that just because a hypothesis test indicates a relationship exists between an intervention and an outcome, there is a difference between groups, or there is a correlation between two constructs, it does not always provide a default measure for its importance. Although relationships are significant, they can be very minute relationships, very small differences, or very weak correlations. In the end, we need to ask whether the relationships or differences…
