How do ethics affect your chosen level of significance?
I am not sure if I understand what the instructor is wanting can some look at my answer and see if I am close and if I am missing something
The level of significance to my understanding is Whenever research is done there is always a chance, a particular outcome will occur that would bring up an false statement that is untrue this happen quite a bit with human research. Through chance the outcomes that is observed makes the researcher unsure of result. This reasonable doubt can be brought about a person moral or ethics.In the finding. My moral value is to find the truth so I would say that I wanted to be 100% sure I have the correct understanding of the result and not a false rating.
Am I understanding this question correct or can some please explain what the instructor might be wanting
In terms of statistics, you can never be 100% sure. I prefer using the .01 level vs. the .05 level, to be a little more certain of my conclusions. Replication can reduce the error even more.
Another thing you might want to consider is practical significance. Even though group differences might be statistically significant, the differences would not help you make many decisions. For example, one study found a significant difference in height between various levels of business management. However, if I remember correctly, the differences between various levels was about 1/4 inch! This doesn't allow serious decision making in terms of hiring for management positions.
I hope this helps. Thanks for asking.
