â€1.‬ â€Specific - Relating to a particular category‬ â€2.‬ â€Constitute - to be made up of, to compose, to form‬ â€3.‬ â€Naturalistic observation - research method in which the psychologist observes the‬ â€subject in a natural setting without interfering.‬ â€4.‬ â€Case study - research method that involves an intensive investigation of one or more‬ â€participants.‬ â€5.‬ â€Longitudinal study - research method in which data are collected about a group of‬ â€participants over a number of years to assess how certain characteristics change or‬ â€remain the same during development.‬ â€6.‬ â€Cross-sectional study - research method in which data are collected from groups or‬ â€participants of different ages and compared so that conclusions can be drawn about‬ â€differences due to age.‬ â€7.‬ â€Correlation - the measure of a relationship between two variables or sets of data.‬ â€8.‬ â€Variable - any factor that is capable of change.‬ â€9.‬ â€Experimental group - the group to which an independent variable is applied.‬ â€10.‬â€Control group - the group that is treated in the same way as the experimental group‬ â€except that the experimental treatment (the independent variable) is not applied.‬ â€11.‬â€Eliminate - to remove or get rid of‬ â€12.‬â€Evaluate - to determine the significance of‬ â€13.‬â€Self-fulfilling prophecy - a situation in which a researcher's expectations influence that‬ â€person’s own behavior, and thereby influence the participants behavior.‬ â€14.‬â€Single-blind experiment - an experiment in which the participants are unaware of who‬ â€received the treatment.‬ â€15.‬â€Double-blind experiment - an experiment in which neither the experimenter nor the‬ â€participants know which participants received which treatment.‬ â€16.‬â€Placebo effect - a change in a participant's illness or behavior that results from a belief‬ â€that the treatment will have an effect rather than from the actual treatment.‬ â€17.‬â€Statistics - the branch of mathematics concerned with summarizing and making‬ â€meaningful inferences from collections of data.‬ â€18.‬â€Significant -‬ â€19.‬â€Descriptive statistics - the listing and summarizing of data in a practical and efficient way.‬ â€20.‬â€Frequency distribution - an arrangement of data that indicates how often a particular‬ â€score or observation occurs.‬ â€21.‬â€Normal curve - a graph of frequency distribution shaped like a symmetrical, bell shaped‬ â€curve, a graph of normally distributed data.‬ â€22.‬â€Central tendency - a number that describes something about the average score of‬ â€distribution variance.‬ â€23.‬â€Standard deviation - a measure of variability that describes an average distance of every‬ â€score from the mean.‬ â€24.‬â€Variance - a measure of variability that is the mean of the squares of the deviations from‬ â€the mean of the set of data.‬ â€25.‬â€Correlation coefficient - describes the direction and strength of the relationship between‬ â€two sets of variables.‬ â€26.‬â€Inferential statistics - numerical methods used to determine weather research data‬ â€support a hypothesis or weather results were due to chance.‬
