Question

josh had a skin fold measurement done at the gym to determine his body composition. based on what you know about this test, which of the following statements best describes the information he has learned. a. it is an easy test that is always reliable, but it provides little detail about ones body composition. b. it can be difficult to determine ones body fat because the test administrator can easily make an error. c. it measures the skins thickness on ones leg and forearm. d. it is one of the most accurate and expensive tests available.

Explanation:

measurements rely on the tester's skill to correctly pinch and measure skin folds; human error in placement, pressure, or reading the caliper can lead to inaccurate body fat calculations. Option A is wrong because the test is not always reliable. Option C is incorrect as skin fold tests typically measure sites like the tricep, subscapular, or thigh, not just leg and forearm. Option D is wrong because skin fold tests are low-cost and not among the most accurate body composition tests (methods like DEXA are more accurate and expensive).
