The Normality Test Calculator determines whether a dataset follows a normal distribution by computing skewness and kurtosis. Skewness measures the asymmetry of the data, while kurtosis measures how heavy or light the tails are compared to a normal distribution. When both skewness and kurtosis values are close to zero, the dataset is approximately normal. This calculator helps in statistical analysis by assessing the distribution shape before applying tests that assume normality, ensuring accurate and reliable results in research and data interpretation.
