The random-number generators in Scientific Notebook give you a set of random numbers from one of several families of distribution functions. The choices in the dialog box are Beta, Binomial, Cauchy, Chi-Square, Exponential, F, Gamma, Normal, Poisson, Student's t, Uniform, and Weibull. From the Statistics submenu, choose Random Numbers. Choose a distribution from the dialog box, specify how many random numbers you want, and enter appropriate parameters. Following are sample results.
