This wonderfully animated applet helps users understand the sample mean's properties, using simulated fish length data which is assumed to come from a normal distribution. Users can choose the sample ...

Normal, or Gaussian, distribution describes a pattern where values in your defined range occur more frequently around a center point, or mean. Using the sales projection example, you observe that ...

The central limit theorem (CLT) states that the distribution of a random variable in a sample will begin to approach a normal distribution as the sample size becomes larger, regardless of the true ...

Gaussian distribution is a statistical concept that is also known as the normal distribution. For a given set of data, the normal distribution puts the mean (or average) at the center and standard ...

We study the asymptotic covariance function of the sample mean and quantile, and derive a new and surprising characterization of the normal distribution: the asymptotic covariance between the sample ...

PSDs characterized by a large long size tail can be described by the power-law relationship between the particle number and size using log-Gaussian and log-normal distribution. Power law distribution ...
