Simple to use, Randov finds percentiles and cumulative probabilities for some common probability distributions: normal (Gaussian), Snedecor's F, Student's t, exponential, Poisson, binomial, and geometric. With this mobile application, you won't ever need to use a statistics textbook appendix, formula, or an expensive graphing calculator to find probabilities/p-values! In the screenshot below, a z score calculation is shown: the mean and standard deviation are set to 0 and 1, respectively. The chance of a z-score less than 1.791 (input value) equals 0.963 (output value). Also, The z-score corresponding to a cumulative probability of 0.348 (input value) equals -0.391 (output value). In addition, two random number generators (discrete and continuous) are included.
