construct - CORRECT ANSWER An abstract quality, such as intelligence or motivation, that is not observable and is difficult to measure.mode - CORRECT ANSWER The most frequent single score in a distribution.experimental methods - CORRECT ANSWER Research procedures that are distinguished by random assignment of participants to conditions and the manipulation of independent variables.archival research - CORRECT ANSWER Research relying on secondary data sets that were collected either for general or specific purposes identified by an individual or organization.extraneous variable - CORRECT ANSWER Anything other than the independent variable that can contaminate our results or be thought of as an alternative to our causal explanation; also called a confounding variable.variance - CORRECT ANSWER A useful measure of dispersion reflecting the sum of the squared differences between each score and the mean of the group divided by the number of total scores.interrater reliability - CORRECT ANSWER The extent to which multiple raters or judges agree on ratings made about a particular person, thing, or behavior.mean - CORRECT ANSWER The arithmetic average of a group of scores, typically the most useful measure of central tendency.statistic - CORRECT ANSWER An efficient device for summarizing in a single number the values, characteristics, or scores describing a series of cases.independent variable - CORRECT ANSWER A variable that is systematically manipulated by the experimenter or, at the least, measured by the experimenter as an antecedent to other variables. 2 / 4

deduction - CORRECT ANSWER An approach to science in which we start with theory and propositions and then collect data to test those propositions�working from theory to data.range - CORRECT ANSWER The simplest measure of dispersion, reflecting the spread of scores from the lowest to the highest.predictive validity - CORRECT ANSWER The extent to which test scores obtained at one point in time predict criteria obtained in the future.case studies - CORRECT ANSWER Examinations of a single individual, group, company, or society.causal inference - CORRECT ANSWER A conclusion, drawn from research data, about the likelihood of a causal relationship between two variables.internal consistency - CORRECT ANSWER An indication of the extent to which individual test items seem to be measuring the same thing.unobtrusive naturalistic observation - CORRECT ANSWER An observational technique whereby the researcher unobtrusively and objectively observes individuals but does not try to blend in with them.content validity - CORRECT ANSWER The degree to which a test or predictor covers a representative sample of the quality being assessed.hypothesis - CORRECT ANSWER A tentative statement about the relationship between two or more variables.parallel forms reliability - CORRECT ANSWER The extent to which two independent forms of a test are equivalent measures of the same construct; sometimes called equivalent forms reliability or a coefficient of equivalence.reliability - CORRECT ANSWER The consistency or stability of a measure. 3 / 4

random assignment - CORRECT ANSWER The procedure by which research participants, once selected, are assigned to conditions such that each one has an equally likely chance of being assigned to each condition.coefficient of determination - CORRECT ANSWER he percentage of variance in a criterion that is accounted for by a predictor.manipulation - CORRECT ANSWER The systematic control, variation, or application of independent variables to different groups of participants.dependent variable - CORRECT ANSWER The variable of interest, or what we design experiments to assess.informed consent - CORRECT ANSWER Participants signifying (usually in writing) their willingness and desire to participate in a particular research study after being provided with important and relevant information about the risks, procedures, and benefits of such participation.theory - CORRECT ANSWER A set of interrelated constructs (concepts), definitions, and propositions that present a systematic view of a phenomenon by specifying relations among variables, with the purpose of explaining and predicting the phenomenon.experience sampling methodology (ESM) - CORRECT ANSWER A technique that allows researchers to obtain repeated real-time reports of phenomena such as moods and emotions through the use of technology such as personal digital assistants (PDAs).internal validity - CORRECT ANSWER The extent to which we can draw causal inferences about our variables.measurement - CORRECT ANSWER The assignment of numbers to objects or events using rules in such a way as to represent specified attributes of the objects.normal distribution - CORRECT ANSWER A mathematically based distribution depicted as a bell-shaped curve, in which most of the observations cluster around the mean and there are few extreme observations.
