    Correlation Coefficient Question

    Any help on this math problem would be greatly appreciated. Thanks

    A high correlation coefficient indicates that a strong relationship exists. Is a positive correlation coefficient of +.68 stronger than a negative correlation coefficient of -.68? Explain

    They have the same strength, one is positively correlated the other negatively correlated.

    Example of a positive correlation is time spent studying vs mark/grade recieved. The grade should increase as time spent studying increases.

    Example of a negative correlation is time spent training for a runnig race vs time taken to run the race. As time spent training increases time taken to run the race should decrease.
