Case study
Terms in this set (12)
Case study
an in-depth investigation of behaviour or event in an individual, a small group or a situation. No generalisations can be made to the broader public from a case study.
Conclusion
a decision or judgement about the meaning of the results of a research investigation
Confounding variable
a variable other than the independent variable that has an unwanted effect on the dependent variable, making it impossible to determine which of the variables produces the change in the independent variable.
Convenience sampling
selecting participants who are readily available without any attempt to make the sample representative of a population; also called opportunity sampling.
Counterbalancing
arranging the order that the conditions of a repeated measures experiment are experienced by the participants so that each condition occurs equally often in each position; commonly used to control order effects.
Descriptive statistics
statistics used to analyse, organise, summarise, describe important features of the data so that they can be more easily interpreted and communicated.
Ethics
standards that guide individuals to identify good, desirable and acceptable conduct.
Experimental group
the group of participants in an experiment that is exposed to the independent variable.
Experimental effect
the change in a participant's response because of the researcher's expectations, biases or actions, rather than the effect of the independent variable.
**Extraneous variable
any variable other than the independent variable that can cause a change in the independent variable and therefore affect the results of the experiment in an unwanted way.
**Generalisation
a decision or judgement about how widely the findings of a study can be applied.
Inferential statistics
mathematical procedures used to judge whether the results for a sample would also occur in the population from which the sample was drawn; also used to estimate hoe likely it is that the results for a study occurred by chance.
