Margin of Error: Margin of error is a measure that quantifies how much sampling error can be expected in an estimate. It represents a range within which we expect our estimate to fall with a certain level of confidence.
Random Sampling: Random sampling is a method where each member of a population has an equal chance of being selected for inclusion in a sample. It helps reduce bias and ensures that samples are more representative.
Sample Size: Sample size refers to the number of individuals or observations included in a sample. A larger sample size generally reduces sampling error as it provides more accurate estimates.
