Types of Reliability
A team of researchers develops a new questionnaire designed to measure an individual's level of creativity. Which of the following outcomes would provide the strongest evidence that the new questionnaire is reliable?

When this process is repeated with other children, the two researchers' scores continue to show no relationship to each other. Based on this information, what is the most significant problem with this new checklist?
