Normal Distribution Graph for Statistics

An essential and clear visual representation of a normal distribution, often referred to as the bell curve. This graph effectively illustrates how data points are distributed around the mean, with vertical lines distinctly marking the standard deviations from the center. It prominently features the empirical rule, demonstrating that approximately 68% of data falls within one standard deviation, 95% within two, and 99.7% within three standard deviations. This illustration is fundamental for anyone looking to grasp core statistical concepts such as data spread, probability, and the characteristics of normally distributed datasets.
