Collection Methods
This controlled vocabulary is a DDI Alliance vocabulary. It defines the procedure, technique, or mode of inquiry used to attain the data. The CLOSER version uses the same values but uses bespoke descriptions drawn from the Descriptive Term and Definition fields.

5.2.1 | Observation.Laboratory.Participant | Research method that involves observing and collecting data as they occur without attempting to manipulate any of the independent variables. Observation is conducted in a controlled, artificially created setting. The researcher interacts with the subjects and often plays a role in the situation under observation. |
5.2.2 | Observation.Laboratory.Nonparticipant | Research method that involves observing and collecting data as they occur without attempting to manipulate any of the independent variables. Observation is conducted in a controlled, artificially created setting. There is no interaction between the researcher and his/her subjects. |
5.3 | Observation.ComputerBased | Research method that involves observing and collecting data as they occur without attempting to manipulate any of the independent variables. Type of observation in which data regarding computer usage are being collected by software that can be built into the programme itself or can be a separate programme. |
6 | Experiment | Research method involving the manipulation of some or all of the independent variables included in the hypothesis. |
