The Pearson's r value represents the degree to which within groups variability exists, relative to between groups variability. |

Answer #1

**The Pearson's r value
represents the degree to which X and Y scores covary together
relative to how much X and Y scores vary
separately.**

The formula for Pearson's correlation coefficient is:

or equivalently

It is the degree to which X and Y covary together (Sxy) relative to how much they vary separately (Sxx and Syy)

1. A researcher conducts a survey to determine the relationship
between aptitude for mathematics and musical ability. She finds a
perfect relationship. High levels of mathematics aptitude are
associated with low levels of musical ability. Given this
information, what is the value of the correlation coefficient for
the above study? ______________

The correlation coefficient r is a sample statistic.
What does it tell us about the value of the population correlation
coefficient ρ (Greek letter rho)? You do not know how to
build the formal structure of hypothesis tests of ρ yet.
However, there is a quick way to determine if the sample evidence
based on ρ is strong enough to conclude that there is some
population correlation between the variables. In other words, we
can use the value of r...
