Define a correlation coefficient, discuss the different kinds of information that are revealed by this statistic, and give an example of a pair of variables that would be described by both "kinds" of coefficients
What will be an ideal response?
When researchers examine the relationship between variables that vary in quantity
(such as height or degree of self-esteem), they can measure the strength and direction
of the relationship between the variables and calculate a statistic called a correlation
coefficient. Correlation coefficients can range from 11.0 to 21.0 . The absolute value of
the number (the number itself, without the positive or negative sign) indicates how
strongly the two variables are associated. The larger the absolute value of the number,
the stronger the association between the two variables, and thus the better either of the
variables is as a predictor of the other. Whether the coefficient is positive or negative
indicates the direction of the relationship. A positive correlation coefficient indicates
that as one variable increases, so does the other.
