The ultimate goal of statistics, as Chungara likely presents it, is inference: using sample data to draw conclusions about a larger population. This section of the textbook would cover estimation (confidence intervals) and hypothesis testing (p-values, t-tests, chi-square tests). Here, probability theory becomes the engine. For instance, a pharmaceutical company testing a new drug cannot measure every patient on Earth. Instead, they take a random sample, compute a sample mean, and use probability (via confidence intervals) to state how confident they are that the true population effect lies within a given range. Chungara's approach probably stresses the logic of null hypothesis significance testing (NHST), cautioning against common misinterpretations of p-values. : Tablas de frecuencias unidimensionales y bidimensionales
