| 7429711988 | Hindsight Bias | "I knew it all along" phenomenon. | 0 | |
| 7429711989 | Critical Thinking | can examine assumptions, discern hidden values, evaluate evidence, and asses conclusions. | 1 | |
| 7429711990 | Theory | Explains through an integrated set of principles that organizes observations and predicts behaviors or events. | 2 | |
| 7429711991 | Hypothesis | A testable prediction, often implied by a theory | 3 | |
| 7429711992 | Operational Definition | A statement of the procedures used to define research variables. | 4 | |
| 7429711993 | Replication | The Repetition of a test by different researchers. | 5 | |
| 7429711994 | Case Study | An observation technique in which one person is studied in depth in the hope of revealing universal principles. | 6 | |
| 7429711995 | Survey | A study, generally in the form of an interview or questionnaire, that provides researchers with information about how people think and act. | 7 | |
| 7429711996 | Population | The whole group one wants to study and describe | 8 | |
| 7429711997 | Random Sample | A sample that fairly represents a population because each member has an equal chance of inclusion | 9 | |
| 7429711998 | Naturalistic Observation | Observing and recording behavior in naturally occurring situations without trying to manipulate and control the situation | 10 | |
| 7429711999 | Correlation | Two things closely varying together. | 11 | |
| 7429712000 | Correlation Coefficient | A measure of the extent to which two factors vary together, and thus of how well either factor predicts the other. | 12 | |
| 7429712001 | Scatterplot | A graphed cluster of dots, each of which represents the values of two variables. | 13 | |
| 7429712002 | Illusory Correlation | The perception of a relationship where none exists | 14 | |
| 7429712003 | Experiment | A research method in which an investigator manipulates one or more factors (independent variables) to observe the effect on some behavior or mental process (the dependent variable). By random assignment of participants, the experimenter aims to control other relevant factors. | 15 | |
| 7429712004 | Random Assignment | Assigning participants to experimental and control conditions by chance, thus minimizing preexisting differences between those assigned to the different groups. | 16 | |
| 7429712005 | Double-Blind Procedure | An experimental procedure in which both the research participants and the research staff are ignorant (blind) about whether the research participants have received the treatment or a placebo. Commonly used in drug-evaluation studies. | 17 | |
| 7429712006 | Placebo Affect | A response to a fake drug, caused by subjects' belief that they are taking real drugs | 18 | |
| 7429712007 | Experimental Group | A subject or group of subjects in an experiment that is exposed to the factor or condition being tested. | 19 | |
| 7429712008 | Control Group | A group separated from the rest of the experiment where the independent variable being tested cannot influence the results | 20 | |
| 7429712009 | Independent Variable | The experimental factor that is manipulated; the variable whose effect is being studied. | 21 | |
| 7429712010 | Confounding Variable | A factor other than the independent variable that might produce an effect in an experiment. | 22 | |
| 7429712011 | Dependent Variable | The outcome factor; the variable that may change in response to manipulations of the independent variable. | 23 | |
| 7429712012 | Mode | A measure of central tendency for a distribution, represented by the score that occurs more often than any other. | 24 | |
| 7429712013 | Mean | Average | 25 | |
| 7429712014 | Median | A measure of center in a set of numerical data. The median of a list of values is the value appearing at the center of a sorted version of the list - or the mean of the two central values if the list contains an even number of values. | 26 | |
| 7429712015 | Range | Distance between highest and lowest scores in a set of data. | 27 | |
| 7429712016 | Standard Deviation | A computed measure of how much scores vary around the mean score. | 28 | |
| 7429712017 | Normal Curve | the symmetrical bell-shaped curve that describes the distribution of many physical and psychological attributes. Most scores fall near the average, and fewer and fewer scores lie near the extremes. | 29 | |
| 7429712018 | Statistical Significance | A measure of confidence that the results obtained are "real," rather than due to random chance. | 30 | |
| 7429712019 | Culture | Shared Ideas and behaviors that one generation passes on the the next. | 31 | |
| 7429712020 | Informed Consent | An ethical principle requiring that research participants be told enough to enable them to choose whether they wish to participate. | 32 | |
| 7429712021 | Debriefing | Any information withheld from subject prior to or during experimentation must be reveled | 33 |
