INDEPENDENT T-TEST - The Student's t or T-test allows you to evaluate two independent samples for significant differences between their means. An example would be the sprint times of two groups of athletes running under different conditions.
In order to evaluate the significance of the calculated t value, you will need the *** table of critical t values which is listed in most books on statistics. *** If the calculated t value is greater than the tabled value for t, the difference between the sample means is significant - in other words, the differences did not occur because of chance.

En el ejemplo previo con 20 niños, los grados de libertad son 18 y ***el valor de la tabla de la t de student*** para una seguridad del 95% es de 2.10 y para un 99% de seguridad el valor es 2.88. (Tabla 2)
