# Statistics for Enterprise Data Analysis

## Objectives

This curricular unit aims at supplying to the students the theoretical and practical knowledge about methodologies on summarizing data, and parametric statistical inference. Students will explore the core principles of statistics, from both the conceptual and applied perspectives. The students will acquire competences related to descriptive statistics, random variables, sampling and confidence intervals, hypothesis testing, regression model and time series linear models. The students will clearly understand the conditions of applicability of each procedure. The concepts and principles will be applied and discussed using the environment, functions, and visualizations of R using real-world concepts applicable to many industries, including medical, business, sports, insurance, etc.
