| 4782331158 | Hindsight Bias | 1) the tendency to believe, after learning an outcome, that one would have foreseen it. Also known as the "I knew it all along" phenomenon. 2) idea that you seen what happened before it actually happened | 0 | |
| 4782334213 | Critical Thinking | 1) thinking that does not blindly accept arguments and conclusions. Rather, it examines assumptions, discerns hidden values, evaluates evidence, and assesses conclusions. 2) Thinking that needs more to prove | 1 | |
| 4782336483 | Theory | 1) an explanation using an integrated set of principles that organizes observations and predicts behaviors or events. 2) a challenged idea for explaining science | 2 | |
| 4782356994 | Hypothesis | 1) a testable prediction, often implied by a theory. 2) an educated guess | 3 | |
| 4782360704 | Operational Definition | 1) a statement of the procedures (operations) used to define research variables. i.e. Human intelligence may be operationally defined as what an intelligence test measures. 2) procedures that measures to define something EX: love-the number of times someones says "I Love You" | 4 | |
| 4782362887 | Replication | 1) repeating the essence of a research study, usually with different participants in different situations, to see whether the basic finding extends to other participants and circumstances. 2) repeating a procedure | 5 | |
| 4782364033 | Case study | 1) an observation technique in which one person is studied in depth in the hope of revealing universal principles. 2) studying one person to help the majority | 6 | |
| 4782365838 | Survey | 1) a technique for ascertaining the self-reported attitudes or behaviors of a particular group, usually by questioning a representative, random sample of the group. 2) questionare | 7 | |
| 4782367798 | Population | 1) all the cases in a group being studied, from which samples may be drawn. Note: Except for national studies, this does NOT refer to a country's whole population 2) all people that can be studied | 8 | |
| 4782369539 | Random sample | 1) a sample that fairly represents a population because each member has an equal chance of inclusion. 2) a fair part of the population used to study | 9 | |
| 4782372344 | Naturalistic Observation | 1) observing and recording behavior in naturally occurring situations without trying to manipulate and control the situation. 2) describes behavior with the subject in their natural environment | 10 | |
| 4782374097 | Correlation | 1) a measure of the extent to which two factors vary together, and thus of how well either factor predicts the other. 2) measuring between two things that help make predictions |  | 11 |
| 4782375206 | Correlation Coefficient | 1) a statistical index of the relationship between two things (from -1 to +1). 2) value of a correlation's ranges |  | 12 |
| 4782376952 | Scatterplot | 1) a graphed cluster of dots, each of which represents the values of two variables. The slope of the points suggests the direction of the relationship between the two variables. The amount of scatter suggests the strength of the correlation (little scatter indicates high correlation). 2) a graph that plots dots for research |  | 13 |
| 4782378163 | Illusory Correlation | 1) the perception of a relationship where none exists 2) a false relationship between two things | 14 | |
| 4782381851 | Experiment | 1) 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. 2) scientist controls factors to get results (cause and effect) | 15 | |
| 4782383218 | Random Assigment | 1) assigning participants to experimental and control groups by chance, thus minimizing preexisting differences between those assigned to the different groups. 2) randomly assigning people to groups | 16 | |
| 4782385059 | Double-Blind Procedure | 1) 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 the placebo. Commonly used in drug-evaluation studies. 2) both the participants and staff don't know who is reciving treatment | 17 | |
| 4782386627 | Placebo Effect | 1) experimental results caused by expectation alone; any effect on behavior caused by the administration of an inert substance or condition, which the recipient assumes is an active agent. 2) idea that you believe that you are getting better but you are the same as before (the use of sugar pills) | 18 | |
| 4782388910 | Experimental group | 1) in an experiment, the group that is exposed to the treatment, that is, to one version of the independent variable. 2) group receiving treatment | 19 | |
| 4782391736 | Control group | 1) in an experiment, the group that is NOT exposed to the treatment; contrasts with the experimental group and serves as a comparison for evaluating the effect of treatment. 2) group not receiving treatment | 20 | |
| 4782393073 | Independent Variable | 1) the experimental factor that is manipulated; the variable whose effect is being studied. 2) the variable that is changed to create outcome | 21 | |
| 4782395497 | Confounding Variable | 1) a factor other than the independent variable that might produce an effect in an experiment. 2) anything that unfairly changes the experiment | 22 | |
| 4782396946 | Dependent Variable | 1) the outcome factor; the variable that may change in response to manipulations of the independent variable. 2) the variable that is changed and measured | 23 | |
| 4782397685 | Mode | 1) the most frequently occurring score(s) in a distribution. 2) most frequent appearing | 24 | |
| 4782401345 | Mean | 1) the arithmetic average of a distribution, obtained by adding the scores and then dividing by the number of scores 2) average of the total | 25 | |
| 4782402633 | Median | 1) the middle score in a distribution, half the scores are above it and half are below it. 2) the middle number | 26 | |
| 4782403717 | Range | 1) the difference between the highest and lowest score in a distribution. 2) the highest minus the lowest score | 27 | |
| 4782405213 | Standard Deviation | 1) a computed measure of how much scores vary around the mean score. 2) how far a group falls from mean | 28 | |
| 4782406674 | Normal Curve | 1) a symmetrical, bell-shaped curve that describes the distribution of many types of data; most scored fall near the mean (68 percent fall within one standard deviation of it) and fewer and fewer near the extremes. 2) a bell shaped curve that shows mean | 29 | |
| 4782407772 | Statistical Significance | 1) a statistical statement of how likely it is that an obtained result occurred by chance. 2) how likely it was caused by chance (95% or better) | 30 | |
| 4782409013 | Culture | 1) the enduring behavior, ideas, attitudes, and traditions shared by a group of people and transmitted from one generation to the next. 2) shared group of people with similar believes and ideas | 31 | |
| 4782411607 | Informed Consent | 1) an ethical principle that research participants be told enough to enable them to choose whether they wish to participate 2) to tell the participants a little info and ask for permission before starting an experiment | 32 | |
| 4782412831 | Debriefing | 1) the postexperimental explanation of a study, including its purpose and any deceptions, to its participants 2) explaining for the experiment after completing | 33 |
