You must be able to explain the mechanisms behind these concepts because entry-level statistics questions for a data analyst interview often revolve around sampling, the generalizability of results, etc. Using confidence intervals, you can estimate the population parameters. In contrast, inferential statistics allows you to formulate and test hypotheses for a sample and generalize the results to a broader population. You can present those using tables and data visualization methods like box plots and histograms. The former summarizes the characteristics and distribution of a dataset, such as mean, median, variance, etc. What Is the Difference Between Descriptive and Inferential Statistics?ĭescriptive and inferential statistics are two different branches of the field.
