Definitions:

Unbiased Estimator

A statistical estimator that, on average, accurately reflects the parameter it estimates, meaning its expected value is equal to the true value of the parameter.

Standard Error

A statistical measure that quantifies the amount of variability in the sampling distribution of a statistic, often used in the context of mean or proportion.

Sample Size

The number of observations or data points that form part of a sample taken from a larger population for the purpose of statistical analysis.

Point Estimate

A single value that serves as the best guess or best estimate of a population parameter based on sample data.
