The Deep Dive

True! The Central Limit Theorem states that as the sample size increases, the sampling distribution of the sample mean will approach a normal distribution, regardless of the shape of the original distribution of . Typically, a sample size of 30 or more is considered adequate for this approximation to hold, particularly when dealing with skewed distributions.
However, if the underlying population distribution is normal, even smaller sample sizes can yield a normally distributed . So, if your population is perfectly normal, you could work with just a few samples and still be golden!
