How does σ affect the graph of function f? 3  Use the sliders to set σ = 1 and change μ. How does μ affect the graph of function f? 4  A standard normal distribution is a normal distribution given by function f above with μ = 0 and σ = 1. Set μ = 0 and σ = 1 to obtain a standard normal distribution and take note of its properties such as symmetry with respect to y axis. More References and linksstatistics tutorials.
