What profound phenomenon does the 'Central Limit Theorem' mathematically guarantee regarding sample means?
Test yourself: pick an answer
Reveal answer & explanation
Correct answer: C) As the sample size increases, the sampling distribution of the mean approaches a normal, bell-shaped distribution, regardless of the population's original shape.
Explanation
The Central Limit Theorem asserts that if you take sufficiently large samples (usually n > 30), the distribution of those sample means will look like a normal distribution, even if the underlying population is wildly skewed.
