Sampling: Sampling refers to the selection of a subset of individuals from a larger population for inclusion in a poll or survey. It aims to ensure that the selected sample represents the characteristics and diversity of the whole population.
Margin of error: The margin of error indicates the range within which survey results are expected to fall due to random sampling variability. It helps assess how reliable and accurate poll results are.
Exit polls: Exit polls are conducted outside polling places during elections, where voters voluntarily share who they voted for as they leave. These polls provide early insights into election outcomes but can also have limitations due to self-selection biases.
