Comparing Normal and Student's t-Distributions
Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
The standard normal distribution (blue) with mean 0 and standard deviation 1 and Student's 
-distribution (red) become very similar as the degrees of freedom for the 
-distribution increase. The left panel displays the two probability density functions (PDFs) and the right panel displays the two cumulative distribution functions (CDFs).
