Polls are surveys conducted to gather opinions or preferences from a group of people. They are often used in politics, marketing, and social research to understand public sentiment on various issues. Polls can be conducted through phone interviews, online questionnaires, or in-person surveys, and the results are typically presented as percentages or trends. In the context of elections, polls help gauge voter intentions and predict outcomes. They can influence campaign strategies and inform candidates about the issues that matter most to their constituents. However, the accuracy of polls can vary based on sample size, methodology, and timing.
