## Sample Size Determination

Sample size determination is the mathematical process of calculating the number of observations required to achieve a desired level of statistical power. In the context of cryptocurrency, where historical data is often limited, determining the correct sample size is crucial for avoiding overfitted models.

If the sample is too small, the study will lack the power to detect true market anomalies, leading to unreliable results. Conversely, excessively large samples can incorporate outdated market regimes that no longer exist.

Analysts must weigh the need for sufficient data against the relevance of that data in rapidly changing digital asset markets. This process involves estimating the expected effect size and the variance of the asset returns.

Proper sample sizing ensures that the conclusions drawn from derivatives data are credible and actionable. It is a fundamental step in designing rigorous quantitative trading systems.
