| What kind of ideas cannot be subjected to scientific research? | Ideas that are not researchable or can be confirmed or refuted. i.e. Abortion |
| What is the purpose of reviewing the literature prior to doing a study? | It will tell you if the research has already been done; method ideas; point out limitations; need for special equipment; needed information |
| What is a research problem and how does this differ from a research hypothesis? | Resarch problem is the question, the hypothesis is the probable answer. |
| Why must research problems be stated in very specific form? | Problem should express relationship. Problem should be a question. Should be able to be empircialy tested. |
| What is the difference between a research and null hypothesis? | Resarch hypothesis is tested and is expected to be true. Null hypothesis is tested and is expected to be false. |
| Why is the null hypothesis tested as opposed to the research hypothesis? | Because it is more accurate to refute a null hypothesis because it states that there is NO relationship. If there is just a little then the research hypothesis can be further tested. |
