This example demonstrates the graph of a normalized IQ distribution with a mean of 100 and a standard deviation of 15. It involves core mathematical concepts such as normal distribution, mean, standard deviation, probability density function, and histogram. The construction uses commands like Normal, Intersect, Segment, and Line, along with objects like σ, f, eq1-7, A-J. It is suitable for high school and above students learning about normal distribution in statistics.
