Opinion polls are surveys conducted to gauge public sentiment on various topics, such as political preferences, social issues, or consumer behavior. They typically involve asking a sample of people questions to understand their views and opinions. The results can help predict outcomes, such as election results or the popularity of a product. Polls are often conducted by research organizations and can be carried out through phone interviews, online surveys, or face-to-face interactions. The data collected is analyzed to provide insights into the attitudes of a larger population, making opinion polls a valuable tool for politicians, businesses, and researchers.
