Which MDC value corresponds to the stair climb test expressed in seconds?

Explanation:
Minimal detectable change is the smallest amount of change that can be interpreted as real beyond measurement error, at a given level of confidence. For a timing test like the stair climb, the MDC is expressed in seconds. The value 5.49 seconds represents the MDC_95 for this test, meaning that a change in stair-climb time of about 5.49 seconds or more is needed to be 95% confident that the change reflects a true improvement or decline rather than just measurement noise or natural variability. The other listed times would not meet that threshold for this specific test in this context, so they aren’t the MDC value for the stair climb test.
