IN human and animal behaviour studies it is often necessary to measure a large number of time-intervals—for example, stimulus-response times—and to find the mean and variance of the distribution of ...

When class widths are not equally sized, they are called unequal class intervals. The area of the bar represents the frequency, so to find the height of the bar, divide frequency by the class width.

This article considers how to estimate Bayesian credible and highest probability density (HPD) intervals for parameters of interest and provides a simple Monte Carlo approach to approximate these ...
