This tool lets you calculate the probability that a random variable X is in a specified range, for a variety of probability distributions for X: the normal distribution, the binomial distribution...
This tool lets you highlight an interval under the normal curve, and see immediately the area under the curve for that interval.
This applet lets you take "slices" through a multivariate data set to compare the distribution of a variable without regard for the values of the other variables with the distribution of that...
The controls on this applet let you change the number of trials, the probability of success in each trial, and toggle between viewing either the difference between the number of successes and the...
This tool lets you find areas under the Student-t probability density. The user controls lower and upper bounds; this results in the area under the curve being shaded. Degrees of freedom can also...
