To determine the correct answer to this question, we need to understand what a survey is. A survey is a research method used to collect information or data from a population. It typically involves asking a set of questions to gather specific information that can be analyzed and used to draw conclusions.

Option 1: "It is a research method where the researcher assembles small groups of people." This option is referring to focus groups, which is a specific research method but not the definition of a survey.

Option 2: "It is when only a portion of a population is researched." This option is referring to sampling, which is a method of selecting a representative group within a larger population, but it does not define a survey.

Option 3: "It involves recording actions or events related to buying behavior." This option is describing observational research, which involves observing and recording behavior, but it is not the definition of a survey.

Option 4: "It is a set of questions used for gathering data." This option accurately defines a survey. Surveys typically consist of a series of questions that are designed to collect specific information from respondents.

Therefore, the correct answer is the fourth option: "It is a set of questions used for gathering data."
