The rectum (from the Latin rectum intestinum, meaning straight intestine) is the final straight portion of the large intestine in some mammals, and the gut in others, terminating in the anus. The human rectum is about 12 cm long. At its commencement its caliber is similar to that of the sigmoid colon, but near its termination it is dilated, forming the rectal ampulla. |

A test or an examination (or "exam") is an assessment, often administered on paper or on the computer, intended to measure the test-takers' or respondents' (often a student) knowledge, skills, aptitudes, or classification in many other topics (e.g., beliefs). Tests are often used in education, professional certification, counseling, psychology (e.g., MMPI), the military, and many other fields. The measurement that is the goal of testing is called a test score, and is "a summary of the evidence contained in an examinee's responses to the items of a test that are related to the construct or constructs being measured." Test scores are interpreted with regards to a norm or criterion, or occasionally both. The norm may be established independently, or by statistical analysis of a large number of subjects.
