The 45% approval rate is an example of descriptive statistics, which summarizes and describes a sample or population. It does not involve using the sample to make inferences about the population (statistical inference), nor does it refer to the entire group being studied (population). The sample size of 3,200 voters does not affect the categorization of the statistic as descriptive.
