Final answer:
The characteristics of a test include objectivity, measurable results, specific questions and methodologies, possibility for confounders, and potential disconnection between collected data and the testable question.
Step-by-step explanation:
The characteristics of a test include being objective, providing measurable results, testing a specific question, and supporting a specific methodology. On the other hand, a test may have confounders and the data collected may have little to do with the testable question. It is important for a test to be based on experiments that collect evidence and can be proven wrong. In scientific explanations, subjectivity is not desirable as they should be subject to testing and judged based on objective observations.
