Question

Quizplus · Accepted Answer

When data collected in research are not useful in addressing the issue that the investigator is studying, they are said to lack validity. Validity refers to the extent to which the data measure what they are supposed to measure, and if they do not, then they are not helpful in answering the research question. Reliability refers to the consistency and reproducibility of data, systematic refers to a standardized, organized approach to data collection, and statistical significance refers to the likelihood that observed results are not due to chance. None of these terms directly address the usefulness of the data in addressing the research question.
