- 1Quantitative ResearchUses experiments/surveys to gather data that can be statistically analysed to test particular hypotheses
- 2Qualitative ResearchIn-depth analysis of a small number of participants to gather data that provides a richer/deeper understanding of the topic than that of Quantitative Research
- 3A TheorySystematic way of organising and explaining observations , which includes a set of propositions/statements about the relationships among various phenomena
- 4HypothesisTentative belief about the relationship between two or more variables
- 5VariableAny phenomenon that can differ, or vary, from one situation/person to another.
- 6Continuous VariableA variable that can be placed on a continuum
- 7Categorical VariableVariable that is comprised of groupings/categories
- 8Standardised ProceduresExposing participants in a study to as similar procedures as possible
- 9Populationa larger group to whom research should be applicable
- 10Samplea subgroup of the population that is likely to be representative of the population as a whole
- 11GeneralisabilityApplicability of the findings to the entire population of interest to the researcher
- 12Sampling Biasoccurs when the sample is not representative of the population as a whole.
- 13Internal ValidityMethods that convincingly test the hypothesis
- 14External ValidityFindings can be generalised to situations outside, or external to, the labratory
- 15Measureconcrete way of assessing a variable. Way of bringing an abstract concept down to earth
- 16ReliabilityMeasure's ability to produce consistent results
- 17Retest reliabilitytendency of a test to yield relatively similar scores for the same individual over time
- 18Internal consistencyWhen several ways of asking the same question yield similar results
- 19Interrater Reliabilitywhen two different interviewers rate an individual on some dimension, both should give the person similar scores.
- 20ValidityMeasure's ability to assess the variable it is supposed to assess
- 21Scientific approachUses empirical methods to gain knowledge
- 22Description (Scientific Approach)summarising relationships between variable
- 23Prediction (scientific approach)anticipating future events
- 24Understanding (Scientific approach)Identifying the causes of phenomenon
- 25experimental researchPsychologists manipulate some aspect of a situation and examine the impact on the way participants respond
- 26Control groupneutral condition against which participants in various experimental conditions can be compared.
- 27Descriptive researchdescribes phenomena as they already exist rather than manipulating variables
- 28case studyin-depth observation of one person or a group of people
- 29Naturalistic Observationin-depth observation of a phenomenon in its natural setting
- 30Survey researchasking a large sample of people questions, usually about their attitudes of behaviour through interviews/questionnaires
- 31Random/Stratified Random samplesallow psychologists to gather substantial info about the population by examining representative samples.
- 32Correlational researchassess the degree to which two variables are related
- 33Correlation coefficientquantifies the association between two variables, and ranges from -1.0 to +1.0. A correlation of zero means that two variables are unrelated.
- 34objectivitytaking an impartial and disinterested approach
