methodologies

Question 1

controlled experiment

Answer 1

An experimental investigation of the relationship between one or more independent variables and a dependent variable, controlling all other variables. This may include the use of control groups.

Question 2

case study

Answer 2

An investigation of a particular activity, behaviour, event or problem that contains a real or hypothetical situation and includes the complexities that would be encountered in the real world.

Question 3

fieldwork

Answer 3

Based on inquiry or the investigation of an issue, fieldwork involves observing and interacting with a selected environment beyond the classroom, usually to determine correlation, rather than a causal relationship.

Question 4

correlational study

Answer 4

Planned observation and recording of events and behaviours that have not been manipulated or controlled to understand the relationships/associations that exist between variables, to identify which factors may be of greater importance and to make predictions.

Question 5

classification and identification

Answer 5

Classification is the arrangement of phenomena, objects or events into manageable sets, whereas identification is a process of recognition of phenomena as belonging to particular sets or possibly being part of a new or unique set.

Question 6

literature review

Answer 6

Involves the collation and analysis of secondary data related to other people’s scientific findings and/or viewpoints in order to answer a question or provide background information to help explain observed events, or as preparation for an investigation to generate primary data.

Question 7

Modelling

Answer 7

Involves the construction and/or manipulation of either a physical model, such as a small- or large-scale representation of an object, or a conceptual model that represents a system involving concepts that help people know, understand or simulate the system.

Question 8

simulation

Answer 8

A process of using a model to study the behaviour of a real or theoretical system. The modelling and manipulation of variables in a real system is useful because often the variables cannot be controlled as the system may be too complex, too large or small, too fast or slow, not accessible or too dangerous.
