- 1. a set of mathematical procedures that help psychologists make inferences about what their research data may say about the populations from which the sample data was drawn. It also provides a measure of how likely it is that research results came about by chance
- 2. a measure of variability that is the average difference between each score and the mean of the data set
- 4. in scientific research, a specific, testable proposition about a phenomenon
- 5. numbers that summarise or describe a set of research data
- 9. a research method involving the intensive examination of some phenomenon in a particular individual, group or situation
- 10. a research method that examines relationships between variables in order to analyse trends in data, test predictions, evaluate theories and suggest new hypotheses
- 12. the process of watching without interfering as a phenomenon occurs in the natural environment
- 13. a situation in which the researcher manipulates one variable and then observes the effect of that manipulation on another variable, while holding all other variables constant
- 14. an integrated set of propositions that can be used to account for, predict and even suggest ways of controlling certain phenomena
