Question: 1 / 400

What is a trend line in Tableau?

A function that improves data visibility

An equation that shows the relationship between fields

A trend line in Tableau refers to an equation that shows the relationship between fields in a dataset. By adding a trend line to a visualization, you can summarize and highlight underlying patterns or correlations between the variables being analyzed. Trend lines can be linear or non-linear, depending on the nature of the data and the relationship that exists between the variables. The primary purpose of trend lines is to provide insight into how one variable may predict or affect another over a range of values.

In the context of data analysis, understanding these relationships is crucial for interpreting trends, making informed decisions, or guiding further analysis. While other options might relate to aspects of data visualization or analysis, they do not encapsulate the specific definition and purpose of a trend line in Tableau as accurately as the option indicating that it represents the relationship between fields.
