Public opinion: Public opinion refers to the collective views and attitudes held by members of society on certain issues. It can influence policy decisions and election outcomes.
Sampling: Sampling involves selecting a subset of individuals from a larger population for research purposes. In the context of private opinion polls, it's important that the sample represents the broader electorate accurately.
Margin of error: Margin of error is a statistical measure that indicates how much random sampling variability there is in survey results. A larger margin of error means there is more uncertainty in the poll's findings.
