First, choose the "universe," that is the population the poll aims to measure.
A specific group of individuals, such as a sample population, is typically studied in a scientific poll to gather data and insights on a particular topic or issue. This group is chosen to be representative of the larger population, allowing researchers to draw conclusions that can be generalized.
Pollsters construct a sample in the second step of a scientific poll to ensure that the data collected is representative of the larger population. A well-designed sample helps minimize bias and allows for accurate generalizations about the views and behaviors of the entire population. By using techniques like random sampling, pollsters can achieve a diverse and balanced representation, which enhances the reliability and validity of the poll results.
