Answer: ordinal scale
Explanation:
There are four levels of measurement: Nominal, Ordinal, Interval, and Ratio. In ordinal measurement, the attributes can be rank-ordered, and attribute labels such as "Strongly Disagree" can be used, always keeping in mind that we can assure that “strongly agree” means the subject agrees more than those who “strongly disagree”, but we cannot quantify their satisfaction levels. The Likert scale is an ordinal scale because it doesn´t allow arithmetic operations.
Answer:b) naturalistic observation
Explanation:
Naturalistic observation is a technique under which observation of the subject is done in its natural environment.
Usually this technique is used when lab research will be unreasonable.
How Does Naturalistic Observation Work?
This technique may be used just because people's responses may be more effective when they are in their comfortable environment than when they are in a lab for research purposes.
Sometimes the result of the research are more effective when the behaviour is observed in an exactly moment when it happens. By watching how people respond to certain situations and stimuli in real-life, psychologists can get a better idea of how and why people react.
