Statisticians generally consider a sample size of about 30 to be sufficient for assuming that the sample is large enough to represent the population, fulfilling the requirements for most parametric statistical tests. This is based on the Central Limit Theorem, which states that the distribution of sample means approximates a normal distribution as the sample size becomes larger, typically considered to be around 30 or more.
