CORRELATION COEFFICIENT: ASSOCIATION BETWEEN TWO ...

TUTORIAL | SCOPE. CORRELATION COEFFICIENT: ASSOCIATION . BETWEEN TWO CONTINUOUS VARIABLES. Dr Jenny Freeman and Dr Tracey Young use statistics to calculate the CORRELATION coefficient: the ASSOCIATION BETWEEN two continuous variables Many statistical analyses can be variable is influencing the value of the undertaken to examine the relationship other variable; CORRELATION simply BETWEEN two continuous variables within measures the degree to which the two a group of subjects. Two of the main vary together. A positive CORRELATION purposes of such analyses are: indicates that as the values of one I To assess whether the two variables variable increase the values of the other are associated. There is no variable increase, whereas a negative distinction BETWEEN the two CORRELATION indicates that as the values variables and no causation is of one variable increase the values of implied, simply ASSOCIATION . the other variable decrease.

Pearson's correlation coefficient r can only take values between –1 and +1; a value of +1 indicates perfect positive association (figure 1), a value of –1 indicates perfect negative association (figure 2), and a value of 0 indicates no linear association (figure 3). The easiest way to check whether it
