Curso 3 de 5 en Alfabetización de datos Programa Especializado. This course will introduce you to the linear regression model, which is a powerful tool that researchers can use to measure the relationship between multiple variables. By the end of the course, you should be able to interpret and critically evaluate a multivariate what does the regression line mean analysis.

While graphs are useful for visualizing relationships, they don't provide precise measures of the relationships between variables. Suppose you want to determine how an outcome of interest is expected to change if we change a related variable. We need more than just a scatter plot to answer this question. What should you do, food science and technology course description example, if you want to calculate whether air quality changes when vehicle emissions decline?

What does it mean for a relation to be transitive if you want to calculate how consumer purchasing behavior changes if a new tax policy is implemented? To calculate these predicted effects, we can use a regression model. This module will first introduce correlation as an initial means of measuring the relationship between two variables.

The module will then discuss prediction error as a framework for evaluating the accuracy of estimates. Finally, the module will introduce the linear regression model, which is a powerful tool we can use to develop precise measures of how variables are related to each other.
