What is the term for a method used to obtain self-reported attitudes or behaviors of a group?

The term that accurately describes a method used to obtain self-reported attitudes or behaviors of a group is a survey. Surveys are structured methods of data collection that can include questionnaires or interviews designed to gather information from participants about their beliefs, opinions, or behaviors. They often consist of a series of questions that respondents answer, allowing researchers to quantify and analyze the data effectively.

Surveys are particularly valuable in psychological research because they can capture a wide range of responses from a large number of people, enabling researchers to identify trends, correlations, and patterns in attitudes or behaviors among different demographics. This method is widely used in various fields, including market research, social sciences, and psychology, thereby contributing to our understanding of human behavior and preferences.
