 Inferential Statistics

The use of statistics to draw conclusions about the broader population, based on the results obtained from a sample drawn from the population.

 Parameter

A statistical property of a population, such as the mean or standard deviation. The value of the parameter is estimated from a sample drawn from the population; thus the exact value of the parameter is never known with certainty. The equivalent properties of samples are known as 'statistics'.

 Statistic

A statistical property of a data set, such as the mean or standard deviation. The value of the statistic is calculated using all the members of the data set and is therefore known with certainty.
