| What is it called when a persons vital signs may change due to presence of health care professional? | White Coat Syndrome |
| This measurement strategy includes watching participants perform in a specific setting | Observational |
| This measurement strategy is more subjective and therefor less credible | Observational |
| At time this measurement strategy may be the only way to obtain data | Observational |

| This from of observational study is used if there is concern that subject's behavior will change as a result reactivity | Concealment |
| When a persons behavior changes as a result of being observed | Reactivity |
| This is used to inform subjects after an observation has been made | Debriefing |
| This is the point in an observational study when a person has the right to refuse or question a study | Debriefing |
| When the observer provokes actions from the ones being observed, this is known as an | Intervention |
| Using hidden cameras, tape recorder, or one-way mirrors to watch subjects without their knowledge is known as | Concealment without intervention |
| This observational study is often used with children who need to be watched without their knowledge | Concealment without intervention |
| This type of observation has fallen out of favor due subjects being provoked and observed without their knowledge | Concealment with intervention |
