Final answer:
Quantitative research is beneficial for isolating variables to analyze relationships, though correlation does not guarantee causation. This method is crucial in fields needing high accuracy.
Step-by-step explanation:
True, one of the pros of quantitative research is that it is useful for isolating variables to examine relationships. This method allows researchers to apply statistical methods to analyze data, which can reveal whether and how variables are correlated. However, it is critical to note that correlation does not imply causation, meaning that just because two variables show a relationship, this does not prove that one causes the other.
Quantitative studies often yield empirical evidence that is valuable in many fields, including those requiring precision and accuracy, like medicine or engineering. Experimental designs, for instance, can isolate an explanatory variable to determine its effect on a response variable by using treatments and random assignment to control for lurking variables.
