| Concept | Term used to describe something we cannot directly observe |
| Conception | Mental images for the term, which summarize collections of seemingly related observations and experiences |
| Conceptualization | The process through which we specify what those images (conception) mean when we use a term |
| Operational definition | Indicates precisely how a concept will be measured |
| Operationalization | Measurement Example: Whether or not someone has an eating disorder can be an operationalization (way of measuring) their health. |
| Reliability (in measurement) | Consistency |
| Validity (in measurement) | Accuracy related to what the researcher is attempting to measure. If a measure is not reliable, it cannot be valid. |
| 4 Levels of measurement | Nominal Ordinal Interval Ratio |
| Nominal level of measurement | To name or classify with no order (Ex: racial groups) |
| Ordinal level of measurement | Rank order |
| Interval level of measurement | Equal distance between points, but zero is arbitrary |
| Ratio level of measurement | Equal distance between points, with a true zero |
| Mean Median Mode | Average Middle most Most common/most repeated |
| Cost-effectiveness ratio | Total cost / effectiveness |
| Benefit-cost ratio | Total benefits / total costs |
| Net benefit | total benefits - total costs |
| 3 reasons why the results of evaluation research do not get used | 1 - The information isn't presented in a way that non-researchers could understand 2 - The findings contradict deeply held beliefs 3 - Vested interests (money) |
| Difference between consent and assent form | Assent - Minor's willingness to participate Consent - Adult agreement to participate |
| Difference between anonymity and confidentiality | Anonymity - Researcher cannot identify which response is from which participant Confidentiality - Researcher can identify which response is from which participant, but promises not to publicly identify |
| Key principles of the informed consent process | 1 - Purpose of study 2 - Study procedures 3 - Potential benefits of study 4 - Potential harm from participating in the study 5 - Can withdraw at any time |
| Name of panel whose members review research proposals involving human subjects | Institutional Review Board (IRB) |
