I saw an equation on wikipedia: (http://en.wikipedia.org/wiki/Fermi-Dirac_statistics)
Does anybody know how this is derived?

Variance in particle number is a measure of the spread or variability in the number of particles present in a given sample or population. It is a statistical concept that quantifies the differences between individual values in a dataset, and the average or mean value.
Variance in particle number is important because it provides valuable information about the distribution of particles in a sample. It can help scientists understand the level of heterogeneity in a population and make predictions about the behavior of the particles.
Variance in particle number is calculated by taking the sum of the squared differences between each data point and the mean, and then dividing by the total number of data points. This value is known as the variance and is typically represented by the symbol σ².
The Variance in particle number can be affected by a variety of factors such as the size and type of particles, the method of measurement, and the overall variability in the sample. Other factors such as experimental conditions and human error can also contribute to variability in particle number.
To reduce the Variance in particle number, scientists can use techniques such as controlling experimental conditions, increasing the sample size, and using more precise measurement methods. It is also important to carefully select and prepare samples to minimize any sources of variability.
