The research aims to verify the theory of reliability in the field of physical education, which states that the less homogeneity, the greater the reliability he greater the validity and vice versa.

The researchers used the descriptive approach in a case study method, and in order to obtain reliability , reliability was used by the method of testing and re-testing on some Physical tests, and also in order to obtain homogeneity, statistical methods have been used (standard deviation, coefficient of torsion, coefficient of variation) The two researchers reached a number of conclusions, including that the results of the tests showed that the opposite relationship between homogeneity and reliability , i.e.

the lower the homogeneity, the greater the reliability.

As for validity , it turns out that the relationship is positive, i.e.

the less homogeneity, the less validity .
