- 1Experimental Psychological Research DesignsMnemonic: “The Dependent Variable DEPENDS on the Independent Variable”
- 2Within-Subjects Design
- 3Between Groups Design
- 4Correlational Psychological Research DesignsNO manipulation of variables, rather it is the observation of already existing variables; MUCH less conclusive than experimental design, but still useful.
- 5Descriptive Psychological Research DesignsPurpose is to describe behaviors without assessing relationships
- 6Laboratory Setting (Pro/Con)Great deal of control over variables; Sacrifices naturalistic setting/behavior
- 7Field Setting (Pro/Con)Less control; More naturalistic observation of behavior
- 8Descriptive StatisticsMathematical methods used to organize and summarize, or describe data
- 9Frequency DistributionA summary of how often various scores occur in a sample of scores. Score values are arranged in order of magnitude, and the number of occurrences is recorded.
- 10Descriptive Statistics: Positive Skew
- 11Descriptive Statistics: Negative Skew
- 12Measure of Central TendencyA single number that presents information about the “center” of a frequency distribution
- 13Measure of Central Tendency: ModeThe most frequently occurring score in the distribution.
- 14Measure of Central Tendency: MeanThe sum of a set of scores in a distribution divided by the number of scores.
- 15Measure of Central Tendency: MedianThe score that divides a frequency distribution exactly in half. The same number of scores fall above and below the median.
- 16Rangethe highest score in the distribution minus the lowest score, a simple measure of variability. A measure of variability
- 17Standard Deviationthe square root of the sum of the squared deviations from the mean divided by the number of scores in the distribution. The larger the standard deviation, the more spread out are the scores in a distribution. A measure of variability
- 18VariabilityInformation about the spread of the scores in a distribution
- 19Measuring Variability: The Normal Curve
- 20Inferential StatisticsMathematical methods used to draw conclusions about a population based on a sample of data; ability to make inferential statistics and the scope of the inferences depend on the population and sample of the subject under study.
- 21Inferential Errors: Type I ErrorErroneously concluding that study results are significant
- 22Inferential Errors: Type II ErrorFailing to find a significant effect that does, in fact, exist
- 23Cross-sectional studiesdifferent groups are studied at the same time;
show the effects of time and environment on many different individuals - 24Longitudinal studiesthe same group is studied over time
