The major objectives of the application of statistics to Science and to chemical analysis are to determine the best value of a series of analytical results obtained with a particular sample and to give some indication of the reliability of the analysis.

As scientists, we are interested in finding results that apply to an entire population of people/ or material/ or chemical substance.

There is no doubt that it would be extremely expensive and impractical to analyze the entire population to draw conclusions about certain variables.
Therefore, in most cases we collect data from a small subset of the population (known as sample) and use these data to infer things about the population as a whole. This small sample’s  statistical measurements is the “model” for the entire population.
