Polling methods are techniques used to gather opinions or preferences from a group of people, often referred to as a sample. Common methods include telephone surveys, online polls, and face-to-face interviews. Each method has its advantages and disadvantages, such as cost, speed, and the ability to reach diverse populations. Another important aspect of polling is the design of the questions. Questions can be open-ended, allowing for detailed responses, or closed-ended, providing specific options for answers. Properly designed polls aim to minimize bias and ensure that the results accurately reflect the views of the larger population.
