## Correlation between ring finger length and athletic ability

### Materials

The materials required for this science fair project:

-    10 athletic girls, age 15 years (athletes, tennis players, hockey players, etc.)
-    10 non-athletic girls,  age 15 years
-    A ruler

### Procedure

1.    For this science fair project, the independent variable is the athletic ability of the female participants. The dependent variable is the difference in the length of their index and ring fingers. This is determined by measuring the length of their fingers. The constants (control variables) are the age of the participants and the number of participants in each group.
2.    Select ten girls aged 15 years old randomly from the school sports teams (e.g. hockey, track and field, tennis).

3.    Compare the length of their index fingers and ring fingers on both their right and left hands, using the ruler. Note the number of girls who have longer ring or index fingers, and record your observations in a table, as shown below.

4.    Select another 10 girls aged 15 years old from non-sports clubs and societies. Interview and select only girls who consider themselves non-athletic.

5.    Measure and compare the length of the index and ring fingers of the girls. Note the number of girls who have longer ring or index fingers, and record your observations in a table, as shown below..
