The T-distribution allows us to analyze distributions that are not perfectly normal. It has the following properties: WebIn a perfectly symmetrical distribution, the mean and the median are the same. This example has one mode (unimodal), and the mode is the same as the mean and median. In a symmetrical distribution that has two modes (bimodal), the two modes would be different from the mean and median. The histogram for the data: 4566677778 is not symmetrical. css center form
