BISERIAL CORRELATION COEFFICIENT Meaning and
Definition
-
The biserial correlation coefficient is a statistical measure that quantifies the degree of relationship between a continuous variable and a binary variable. It is commonly used when analyzing data that involve an independent variable that can only take on two values. The coefficient provides information on the strength and direction of the relationship between the two variables.
In essence, the biserial correlation coefficient is a variant of the Pearson correlation coefficient specifically designed for situations involving a continuous variable and a binary variable. It ranges from -1 to +1, where a value of -1 indicates a perfect negative relationship, +1 indicates a perfect positive relationship, and 0 indicates no relationship. The coefficient is calculated by considering the means and standard deviations of both variables, as well as the proportion of individuals in the binary variable.
The biserial correlation coefficient is particularly useful in determining the accuracy of a binary measure given a continuous measure. It helps to assess the extent to which the binary variable differentiates between high and low scores on the continuous variable. For example, it could be deployed to measure the relationship between height (continuous variable) and gender (binary variable) to determine if there is a significant association between height and gender.
Overall, the biserial correlation coefficient is a valuable statistical tool in applied research settings, particularly when analyzing data that contain a continuous variable and a binary variable. It allows researchers to determine the strength and direction of the relationship between these variables, providing valuable insights into their association.
