the correlation coefficient of a data set is -0.833 can I be confident that my predicted value will be close to the actual value? Why or why not?

  1. a number (positive or negative) close to 1 means it is a good approximation.

    review correlation coefficients.

  3. The correlation coefficient for the given data set is= -0.833

    It means there is weak relation between two variables. Negative correlation means, if one quantity is increasing other is decreasing.
    So, the value of -0.833 shows that there is very less correlation between x and y values or two values in data set.
    Also , The correlation can range from -1 to 1, with 0 being no correlation at all. so in this case, -0.833 is close to 0, you would be not confident at all.
    This means your prediction is no better than a random guess.
    So, the chances are very less that predicted value will be reasonably close to the actual value as the points will be far from line of best fit.
