Finite Population Correction

An adjustment made to the standard formula for calculating sample size and variance when the sample size is a significant fraction of the total population.

Non-normal Probability Distribution

Describes a distribution of data that does not follow the normal distribution pattern, showing skewness or kurtosis different from a bell-shaped curve.

Central Limit Theorem

A fundamental statistical theory stating that, given a sufficiently large sample size from a population with a finite level of variance, the mean of all samples from the same population will be approximately equal to the mean of the population.

Synthesis Gas
