Sampling Distribution
A sampling distribution is a probability distribution of a statistic obtained by selecting random samples from a population. It is a fundamental concept in statistics that reveals how sample statistics (like sample means, variances, etc.) are distributed.
Key Aspects:
- The shape of the sampling distribution depends on the size of the sample and the population distribution.
- Larger sample sizes lead to sampling distributions that are more closely concentrated around the true population parameter.
- The Central Limit Theorem states that the sampling distribution of the sample mean approaches a normal distribution as the sample size becomes large.
