Problem Statement

What is a residual plot?

Step-by-Step Explanation

A residual plot helps evaluate whether a regression model fits data well.

  1. Identify what the question is asking. In Data Visualization, this usually means naming the known quantities, the unknown quantity, and the concept that connects them.
  2. Write the relevant definition, rule, or relationship before substituting numbers or manipulating symbols.
  3. Work one step at a time and keep units, signs, and restrictions visible.
  4. Check whether the answer makes sense in the original context.

Final Answer

A residual plot helps evaluate whether a regression model fits data well. The reliable strategy is to start from the definition, apply the correct rule carefully, and then interpret the result in plain language.
