The study of consumer trends can be carried out through many different methods. One of the most commonly used is surveying. Surveys can be sent to panels of respondents, or they can be distributed online. Often, surveys are completed in the form of a group interview, in which both brand representatives and consumers participate. Other methods include observational surveys, in which the researcher observes consumer behavior in stores or other places where consumer-brand interaction may take place. Interview research is also used, to obtain more detailed information about consumer expectations. A quantitative research method, such as survey research and research on online activity, is also used for consumer trend research. Quantitative research helps gain a broader picture of consumers and their behavior. In addition to these methods, consumer trend research can also involve analyzing data from various sources, including public and private sectors. Such data can be effectively used to create models and forecasts on consumer trends.
