Statistical Inference A primary purpose of statistical inference is to develop estimates and test hypotheses about population parameters using information contained in a sample. A parameter is a numerical characteristic of a population. ( , mean and variance). With proper Sampling methods, the sample results can provide good estimates of the population characteristics.
