Definitions:

Stratified Sampling

A method of sampling that divides the population into distinct layers or strata and then randomly selects samples from each stratum.

Confidence Intervals

A range of values, derived from the sample data, that is believed to contain the true population parameter with a certain level of confidence.

Point Estimate

A single value estimate used to approximate a population parameter, derived from sample data.

Margin of Error

A statistic expressing the amount of random sampling error in a survey's results, which represents the extent to which the survey results might differ from the true population values.
