Seventh, because the immune system is weak it cannot kill enough cancer cells and the cancer cells grow out of control. Thus, in summary, the root cause of cancer is microbes and parasites that are in the organs or colon (or bloodstream), which weakens the immune system. However, other things can cause cancer.
Test Reliability and Validity Defined Reliability. Test reliablility refers to the degree to which a test is consistent and stable in measuring what it is intended to measure. Most simply put, a test is reliable if it is consistent within itself and across time.
Human nature, being what it is, generally seems to cause people to want to simplify. information collection and if there is a perceived âreliableâ method or test to use (even if it isnât), they will. Too often any so called FCE tests/evaluations are assumed to be reliable because of. unquestioned repetitive use. The, âWeâve always done it that way so it must be reliable . . .â is. an assertion/assumption as well as an arbitrary conclusion not based on fact.
