Objectives
At the end of the U.C. the student will be able to:
1.1. carry out data analysis, interpret the results obtained and proceed with decision-making;
1.2. analyze a scatter diagram, determine the equation of the regression line, obtain estimates for parameters based on the linear regression model and critically interpret the results obtained.
2. The student will be able to develop logical and analytical reasoning that allows the creation of autonomy in learning.
