How do you verify that a sample of water is safe for drinking?
The microbiological test will identify total coliforms (a type of bacteria) and faecal coliforms in drinking water.

Can You claim validity if there is a causal relationship?
Construct Validity: Assuming that there is a causal relationship in this study, can we claim that the program reflected well our construct of the program and that our measure reflected well our idea of the construct of the measure?
When is validity considered an issue of conclusion validity?
Because the interest is in a relationship, it is considered an issue of conclusion validity. Assume that the study is completed and no significant correlation between amount of training and adoption rates is found. On this basis it is concluded that there is no relationship between the two.
Are there any other tests for specimen validity?
There are additional tests that may be performed in conjunction with the creatinine, SG, and pH specimen validity tests. A test for general oxidants or specific oxidants may be conducted to provide further information regarding the validity of a urine sample.
Is the validity theory impossible to explain adequately?
The theory is general in scope and applicability, well-articulated in its philosophical suppositions, and virtually impossible to explain adequately in a few minutes. As a framework for judging the quality of evaluations it is indispensable and well worth understanding.
