Density curves come in all shapes and sizes and they allow us to gain a quick visual understanding of the distribution of values in a given dataset. In particular, they’re useful for helping us visualize: 1. Skewness Skewness is a way to describe the symmetry of a distribution. Density curves allow us to quickly see … See more Suppose we have the following dataset that shows the height of 20 different plants (in inches) in a certain field: If we created a simple histogram to … See more Density curves have the following properties: 1. The area under the curve always adds up to 100%. 2. The curve will never dip below the x-axis. Keep these two facts in mind … See more WebA probability distribution is a mathematical description of the probabilities of events, subsets of the sample space. The sample space, often denoted by , is the set of all possible outcomes of a random phenomenon being observed; it may be any set: a set of real numbers, a set of vectors, a set of arbitrary non-numerical values, etc.
