El coeficiente puntual biserial
(rpbs) para cada uno de los items del test, considerado como una medida de homogeneidad obtenida por correlacion entre los puntajes que arroja el item y los puntajes totales que arroja el test, se presenta en la figura 3.

Correlation coefficients (Phi, Point Biserial
, Rank Biserial
, Spearman) were used to explore the direction and relative strength of the potential relationship between level of education (no schooling completed, nursery/elementary school, high school, vocational/technical school, college, and university or equivalent), employment status (employed/ unemployed) and working hours (number of hours) with symptoms of CMD (presence/ absence) (27).
s]) is used for ordinal values in which students ranked their perceptions of the GBL experience using Likert scale, and rank biserial

Another test used was the Biserial
Point Correlation Coefficient, which is derived from the Pearson Linear Correlation Coefficient.
a) Pearson Product-Moment Correlation; (b) Point Biserial
Correlation; (c) Spearman Rank-Order Rho Correlation.
For each country, Pearson's or Point Biserial
correlation coefficients were used to explore the direction and relative strength of the potential relationship between stressors (life events and career dissatisfaction) and the outcome measures under study (Portney and Watkins, 2008).
correlation was applied to find out the relation between the disease and the environmental factors.
de Spearman, de Kendall y de Goodman y Kruskal para el primer caso (6), y el coeficiente biserial

regression analysis showed the persistent significance between the serum uric acid level, even after elimination of age and serum creatinine levels.
Next, we conducted a point biserial
correlation to examine the direction and strength of the relationship between LRE and use of an AAC system.
