In a study, there is always the possibility of extraneous variables or unforeseen circumstances that may interfere positively or negatively with the results of the study. There are some ways extraneous variables can be limited or controlled. Additionally, to maintain controls recognized in the study plan, it is important to continuously watch for previous or formerly unidentified extraneous variables that may have an influence and effect on the data you are collecting (Grove, Burns, Gray, 2013).
In the case of my study, demand characteristics, confounding variables, experimenter / investigator effects, participant variables and situational variables may affect the outcome (Cherry, 2016).
Demand characteristics: All participants educational level, zeal to learn and prevent health issues may not be the same. Also, all participants may not be in a supportive environment which may alter outcome.
Experimenter / Investigator Effects: The investigator may unintentionally affect the outcome by showing clues to participants about how they should perform in an individual basis. For example, giving clues to participants in a one on one basis depending on their individual concerns or situation.
Participant variables: Participants may have prior knowledge than others and their health status or any other individual characteristic may not be the same and can affect the outcome in one way or the other.
Situational variables: The nature of participant’s job, stress level, coping mechanism, family issue, income level, divorce, death in the family and other factors (during the study) may also affect the outcome of the study.
