Data is also affected by specific faults, such as unrepresented or underrepresented samples. Limitations of Correlations Limitations of Correlations . Advantage to experimental research Allows drawing of conclusions about the causal relationships among variables. Limitations of Correlational Studies: With either positive or negative correlation, there is no evidence or proof that changes in one variable cause changes in the other variable.
