7. A researcher is investigating verbal behavior among introverts and extroverts. The researcher first tests participants and classifies them as either introverted or extroverted. She then randomly assigns participants to a high-anxiety or a low-anxiety social group and observes the number of words spoken by participants. The researcher wants to learn more about the effects of both personality style (introversion or extroversion) and social situation (high or low anxiety) on verbal behavior. In this case, verbal behavior is defined as the number of verbal communications uttered within a five-minute observation period. What type of design is this

Observation design

Explanation:

Observation design is a type of design that observes ongoing behaviour. A researcher gets its information through actions that are being carried out. It is used predominantly in marketing and social sciences research.

In the research we have a dependent and independent variable.

Independent variable are variable that is varied in an experiment, the independent variable is personality style and its type (introversion and extroversion) and social situation and its type (high and low anxiety) while the dependent variable is verbal behaviour. Verbal behaviour is determined by the action of personality style and social situation this means verbal behaviour cannot stand on its own rather it is a product of some independent variable.

There are two types of observational research, the naturalistic and non participatory.

Naturalistic involves observing things that occurs in nature without influencing it while participation allows an individual to participate to allow proper documentation and this was used in this experiment.
