Answer:
The experimental procedure has high reliability but still it is required to evaluate its validity
Step-by-step explanation:
Reliability and validity are terms used to determine the quality of research, indicating how good is the technique, method and/or test of the experimental procedure. Reliability indicates the consistency of the experimental measurements to be evaluated, while validity indicates the accuracy of these measurements. In this case, the experimental procedure has high-reliability since many researchers obtained the same results independently. Thus, reliability is calculated by comparing different versions of the same measurement (i.e., many researchers measuring the same thing). Moreover, validity still has not been estimated, as this value has to be calculated by comparing the results of other data, models or theories.
