Correlational research can only show that two variables are related, but cannot determine the direction of causation. For example, a correlation may be found between high levels of stress and poor sleep quality, but it is unclear whether stress causes poor sleep or poor sleep causes stress. This ambiguity is a major disadvantage of correlational research. The other options are not true; correlational research can examine multiple variables and it is important to recognize that correlation does not imply causation.
