Margin of Error: The margin of error is a measure of how accurate a prediction or poll result is likely to be. It accounts for uncertainty in data collection and sample size.
Sampling Bias: Sampling bias occurs when certain groups are overrepresented or underrepresented in a poll's sample, leading to inaccurate predictions that do not reflect the larger population.
Voter Volatility: Voter volatility refers to voters changing their opinions or preferences over time, which can make predicting election outcomes more challenging.
