Survey


 * Survey**

A survey is a research method used to extend understanding of an issue or topic by gathering facts, opinions, interests, and attitudes from a representative sample of a population. Conducting an effective survey involves clearly identifying the research question; determining the instrument to be used (for example, questionnaire, test, interview, or attitude scale); determining the population to be surveyed; collecting the data; and tabulating the results. Surveys must be carefully structured and pre-tested and include a high rate of response to be accurate. For validity, surveys must be directed to a representative sample. To ensure a high rate of return, certain strategies must be followed, including identifying the sponsor, inclusion of a cover letter stating the purpose, clear instructions, objective items, attractive format, minimum length, and assurance of anonymity. Questions of confidentiality and ethical considerations must be carefully presented to students prior to administering the survey.

 * Illustrations From The Mathematics Classroom**

Students design a survey in class to look for patterns that relate to specific industries and specific countries. Each student conducts the survey at home to determine where different household appliances and products were manufactured. They then map this information and contribute their findings to a class discussion to compare the validity of their conclusions.
 * Elementary**

Working in small groups, students develop a survey that allows them to answer a research question related to recycling in their community. Each group creates a visual display to explain their methodology and findings.
