1. A health researcher studies the relationship between daily water intake and mental clarity. They calculate a correlation coefficient of 0.29 between drinking more water and improved mental clarity. The researcher concludes that increasing water intake improves mental clarity. Does the researcher's information support the conclusion? Briefly explain your reasoning. Hint you the r value chart in the lesson to help.

Answer

No, the researcher's information does not fully support the conclusion. While a positive correlation of 0.29 suggests *some* relationship between drinking more water and improved mental clarity, it is a weak correlation. The correlation coefficient (r-value) of 0.29 indicates a weak positive linear relationship, meaning the association is not strong. It's possible that other factors contribute to mental clarity, and simply increasing water intake may not be the sole or primary driver of improvement. Correlation does not equal causation.<br />
