Unit 0: Module .04 - .5 Keyterms Flashcards
Correlation
a mutual relationship or connection between two or more things.
Correlation Coefficient
a numerical measure of some type of linear correlation, meaning a statistical relationship between two variables
Variable
an element, feature, or factor that is liable to vary or change.
Satterplot
a graph in which the values of two variables are plotted along two axes, the pattern of the resulting points revealing any correlation present.
Experiment
a scientific procedure undertaken to make a discovery, test a hypothesis, or demonstrate a known fact.
Experiment Group
The group in a research study that receives the drug, vaccine, or other intervention being tested.
Control Group
The group in a experiment that does not go under any change
Random Assignment
every participant having an equal chance of being in either the experimental group or the control group.
Single Blind Procedure
A type of clinical trial in which only the researcher doing the study knows which treatment or intervention the participant is receiving until the trial is over.
Double Blind Procedure
A type of clinical trial in which neither the participants nor the researcher knows which treatment or intervention participants are receiving until the clinical trial is over.
Placebo Effect
a beneficial effect produced by a placebo drug or treatment, which cannot be attributed to the properties of the placebo itself, and must therefore be due to the patient’s belief in that treatment.
Independent Variable
The variable that is changed during the experiment
Confounding Variable
a confounder is a variable that influences both the dependent variable and independent variable
Experimenter Bias
The observer-expectancy effect is a form of reactivity in which a researcher’s cognitive bias causes them to subconsciously influence the participants of an experiment.
Dependent Variable
The variable that is the results
Quantitative Research
the process of collecting and analyzing numerical data to describe, predict, or control variables of interest.
Qualitative Research
gathers participants’ experiences, perceptions, and behavior. It answers the hows and whys instead of how many or how much.
Informed Consent
the process in which a health care provider educates a patient about the risks, benefits, and alternatives of a given procedure or intervention.
Debriefing
a meeting to question someone, typically a soldier or spy, about a completed mission or undertaking.
Illusory Correlation
when we see an association between two variables (events, actions, ideas, etc.) when they aren’t actually associated.
Regression Towards Men
the tendency of results that are extreme by chance on first measurement—i.e. extremely higher or lower than average—to move closer to the average when measured a second time.
Validity
the quality of being logically or factually sound; soundness or cogency
