Abstract

The digit ratio is the ratio of the lengths of different digits or fingers measured from the midpoint of bottom crease where the finger joins the hand to the tip of the finger. An Anthropometric survey was conducted among local students (150 males and 150 females) of SEGi University Malaysia to determine and compare the index finger length with ring finger length (2D:4D ratio) using middle finger as the standard reference point. The data collected by random sampling method were used to calculate the 2D:4D ratio. Statistical Package for the Social Sciences (SPSS) and Students t- test were used to determine the level of significance. From the analysis, the data exhibited females have greater average difference in the 2D:4D ratio compared to males. Meanwhile, 2D:4D ratio of right and left hand were not significant in males (p=0.209) but significant in females (p=0.024). On the other hand, the 2D: 4D difference between males and females for both hands were found not significant (p=0.527 in males, p=0.835 in females). The analysis also demonstrated that males have greater 2D:4D ratio for both hands compared to females. The digit ratio can be correlated with health, behavior and sexuality.

Keywords: digit ratio, 2nd digit - 4th digit ratio, 2D:4D, 2D/4D, digit length.
