Question

When assessing body composition, why should the same technique be used for pre- and post-test comparisons?

Question 9 options:

Some techniques yield estimates of body fat and some yield estimates of bone density


Some techniques are highly accurate and some are usually inaccurate


Some techniques measure in grams and others in ounces


All the techniques are very time-consuming to set up and administer


Each technique might yield slightly different values

Answer 1

Answer: Each technique might yield slightly different values.

Step-by-step explanation:

When you want to compare the features of something before and after a certain event has taken place, it is always best to use the same comparison method as this ensures that there is uniformity of data.

This is the same with body composition. When a certain technique is used to measure body composition before a test, that same technique should be used after the test because different techniques might yield slightly different values and so for the purposes of uniformity of data, it is best that the same technique is used.
