Questions & Step-by-Step Solutions

What is the primary purpose of linear regression?
  • Step 1: Understand that linear regression is a method used in statistics.
  • Step 2: Know that it helps us find a relationship between two or more variables.
  • Step 3: Identify the 'outcome variable' which is what we want to predict (this is a continuous value).
  • Step 4: Recognize the 'predictor variables' which are the factors we use to make our prediction.
  • Step 5: Realize that linear regression creates a line (or equation) that best fits the data points.
  • Step 6: Use this line to make predictions about the outcome variable based on new values of the predictor variables.
