Sample size is the number of observations or participants selected from a population to represent it accurately in a study.

The right sample size ensures results are statistically significant and represent the population accurately without bias.

Population size, confidence level, margin of error, and variability of the data affect sample size.

Confidence level indicates how certain we are that the sample accurately represents the population, usually expressed as a percentage (e.g., 95%).
