Document Summary
Anecdotal evidence: consists of personal stories about specific incidents and experiences. Case study: an in-depth investigation of an individual subject. Confounding of variables: occurs when two variables are linked together in a way that makes it difficult to sort out their specific effects. Control groups: consists of similar subjects who do not receive the special treatment given to the experimental group. Correlation: exits when two variables are related to each other. Correlation coefficient: a numerical index of the degree of relationship between two variables. Correlation research: permits to only describe patterns of behaviour and discover links or associations between variables. Data collection techniques: are procedures for making empirical observations and measurements. Dependent variable: the variable that is thought to be affected by manipulation of the independent variable. Descriptive statistics: used to organize and summarize data. Double-blind procedure: a research strategy in which neither subjects nor experimenters know which subjects are in the experimental or control groups.
