driver."

검증된 단계별 안내

Step 1: Understand the definitions of explanatory and response variables. The explanatory variable (also called the independent variable) is the variable that is used to explain or predict changes in another variable. The response variable (also called the dependent variable) is the outcome or variable that is being predicted or explained.

Step 2: Identify the variables mentioned in the problem. Here, the actuary is interested in the number of hours of safety driving classes and the number of driving accidents for each driver.

Step 3: Determine which variable is used to predict the other. The problem states that the actuary wants to see if the number of hours of safety driving classes can be used to predict the number of driving accidents.

Step 4: Assign the explanatory variable as the number of hours of safety driving classes because it is the predictor variable.

Step 5: Assign the response variable as the number of driving accidents because it is the outcome that is being predicted.

주요 개념

질문에 올바르게 답하기 위해 반드시 이해해야 하는 핵심 개념들은 다음과 같습니다.

Explanatory Variable

The explanatory variable, also known as the independent variable, is the factor that is manipulated or considered as the cause in a study. It is used to explain or predict changes in another variable. In this context, it is the number of hours of safety driving classes.

Response Variable

The response variable, or dependent variable, is the outcome or effect that is measured in a study. It depends on the explanatory variable and reflects the result of interest. Here, it is the number of driving accidents for each driver.

Predictive Relationship

A predictive relationship involves using one variable to forecast or estimate another. Understanding this helps determine how changes in the explanatory variable might influence the response variable, such as predicting accidents based on safety class hours.
