Political science 3n06 2016 lecture 4a sampling distributions. Inferential statistics allow you to draw conclusions about populations you have not measured, on the basis of samples that you have measured. They enable you to calculate how probable it is that your sample results are true for the larger population from which the sample was taken. Note: inferential statistics are only valid for probabilistic samples: i. e. those that have been gathered by epsem . If the sample is not a probabilistic sample then you cannot expect inferential statistics to produce valid results regarding population parameters. To better understand how inferential statistics works it is important to first differentiate between three distributions. The sample the group of cases we actually observe and gather data on. The sampling distribution a theoretical distribution that enables us to: to go from sample statistics to estimations of population parameters.
