Which type of written test item is known for having a 50/50 guessing chance?

• A. Multiple-Choice Questions
• B. True/False Questions
• C. Essay Questions
• D. Fill-In-The-Blank Questions

Answer: (B)

True/False questions are characterized by their binary nature, presenting only two possible answers: true or false. This format inherently provides a 50/50 chance of answering correctly through random guessing, since the respondent must choose between two options. As a result, a test-taker who is uncertain can guess and has a 50% probability of selecting the correct answer. Other types of questions, such as multiple-choice, essay, and fill-in-the-blank, do not offer the same level of guessing probability. Multiple-choice questions often provide several answer choices, which can diminish the chance of random guessing correctly unless the number of options is limited. Essay questions demand detailed, constructed responses that require knowledge beyond simple recognition of concepts, and fill-in-the-blank questions, while occasionally binary in nature, typically have varying levels of complexity that can affect guessing odds depending on the number of blanks and context required to answer correctly.
