Unlock the power of the Central Limit Theorem (CLT) with our intuitive calculator. Easily determine the Z-score for a given sample mean, understand the standard error, and grasp how sample distributions approach normality. Essential for statistical inference and hypothesis testing across various fields.
Formula:
Standard Error of the Mean (SEM) = σ / √n
Z-score (Z) = (X̄ - μ) / SEM
Where:
X̄ = Sample Mean
μ = Population Mean
σ = Population Standard Deviation
n = Sample Size
