Casual conclusions can be drawn. 1 of 31 Field Experiment Research is carried out in a natural enviroment but still has a high degree of control. Many more Ev's which can be difficult to control. 2 of 31 Quasi (Natural) Experiement Researcher has no control over the IV however they will still measure the DV, Therefore the IV occured naturally. 3 of 31 Non-participant Observation Researcher observes behaviour but does not get involved in the activity. 4 of 31 Content Analysis Qualitative materials are analysed for themes and categories, can then be turned into quantitative data. 5 of 31 Structured Interviews Interviews that follow a set format so additional questions can't be asked. 6 of 31 Open Questionnaire Can contain both qualitatve and quantitative questions, open-ended questions require more thought and more than a simple one-word answer. 7 of 31 Closed Questionnaire Can contain both qualitatve and quantitative questions, Closed-ended questions can be answered by a simple yes or no. 8 of 31 Semi-structured Interviews Researcher asks a number of set questions but is able to take the interview in a different direction if needed. 9 of 31 Correlational Analysis Technique for looking at the strength of a relationship between two co-variables, meaning two variables that vary together. 10 of 31 Case Study Normally a longitudinal study where a person or group of people are studied in depth. 11 of 31 Self-reports When people provide information about themselves. 12 of 31 Longitudinal research Research that is carried out over a period of time. 13 of 31 Correlation Determining the extent of an association between two variables 14 of 31 Correlation Coefficient A number between -1 and +1 that tells us how closely to co-variables in a correlation analysis are associated. 15 of 31 Curvilinear Correlation A non-linear relationship between co-variables. 16 of 31 Intervening variable A variable that comes between two other variables which is used to explain the association between these two variables 17 of 31 Linear Correlation A systematic relationship between co-variables that is defined by a straight line. 18 of 31 Scatter Diagram A graphical representation of the association between two sets of scores. 19 of 31 Significance A statistical term indicating that the research findings are sufficiently strong for us to accept the research hypothesis under test. 20 of 31 Cross-sectional Study One group of participants representing one section of society are compared with participants from another group. 21 of 31 Internal Reliability Extent to which a measure is consistent within itsself.(Repeat readings to get same results). 22 of 31 External Reliability The extent to which a measure varies from one use to another.(Redoing the test outside the setting). 23 of 31 Inter-rater Reliability If the measure depends upon interpretation of behaviour, we can compare the results from two or more raters. 24 of 31 Test-retest Reliability The measure is administered to the same group of people twice. 25 of 31 Split-half Reliability Splitting a test in two halves, and comparing the scores in both halves 26 of 31 Sampling The selection of participants from the sampling frame with the aim of producing a representivite selection of people from that group. 27 of 31 Target Population The group of people that the researcher is intrested in and from whom a sample is drawn. Also the group of whom generalisations can be made. 28 of 31 Sampling Frame A list of participants from the target population from which a sample is drawn. 29 of 31 Random Sample A sample of participants produced by using a random technique so that every member of the target population has an equal chance of being selected. 30 of 31 Opportunity Sample A sample of participants produced by selecting people who are most easily available at the time of the study. 31 of 31
