For which of these research situations would you MOST likely calculate a correlation coefficient?

A) independent variable = type of car owned; dependent variable = money spent on gasoline per week
B) independent variable = age; dependent variable = reaction time in milliseconds
C) independent variable = city of residence; dependent variable = miles driven per week
D) independent variable = college major; dependent variable = type of car owned

Correlation Coefficient

A statistical measure that calculates the strength and direction of a linear relationship between two variables, ranging from -1 to 1.

Independent Variable

A variable in an experiment or model that is manipulated or changed to observe its effect on a dependent variable.

Dependent Variable

The variable in an experiment or study that is affected by changes in the independent variable.

  • Acquire knowledge of when and why one should calculate a correlation coefficient in the realm of research.

Final Answer :
B
Explanation :
Correlation coefficient is used to determine the strength and direction of the association between two continuous variables. In this case, the independent variable (age) and dependent variable (reaction time) are both continuous variables and could be analyzed using a correlation coefficient. A, C, and D also involve continuous variables but do not necessarily require a correlation coefficient for analysis.
