Step 1: Have the subject remove as much clothing as possible, including shoes and jewelry, in order to obtain the most accurate assessment.

Percent difference = actual height (m) – average height (m) / average height (m) x 100/1Īctual height: height assessed in this lab.Īverage height: average height according to table 1.3. Step 10: Calculate the percent difference with the following equation and transfer to the individual data sheet: Step 9: Calculate a difference score by subtracting the average height from the measured height and transfer to the individual data sheet. Step 8: Compare the results with the normative data presented in table 1.3 for average height of Americans, and record the result on the individual data sheet. Step 7: To begin interpreting the data, convert (if necessary) the measured height from inches to centimeters and then calculate the average of the three trial measures. Step 6: Repeat steps 2 through 5 twice for a total of three measurements. Step 5: Measure the subject’s height to the nearest tenth of a centimeter (0.1 cm) or to the nearest eighth or quarter of an inch, convert it to meters, and record this value on the individual and group data sheets. If using a physician’s scale, move the hinged lever so it is perpendicular to the graduated vertical rod while resting evenly on top of the subject’s head. Step 4: Lower the headboard so that it rests atop the subject’s head and is perpendicular to the measuring scale. Step 3: Instruct the subject to stand as tall as possible, inhale, and hold his or her breath while looking straight ahead. If using a wall-mounted stadiometer, have the subject stand with the buttocks, scapulae, and heels in contact with the wall. Step 2: Have the subject remove his or her shoes and then stand with his or her back to the stadiometer and heels placed evenly apart. If using a physician’s scale, measure the distance from the scale platform to the hinged horizontal level. Step 1.1: Verify the accuracy of the stadiometer by measuring the distance from the floor to the base to the horizontal headboard. Step 1: Certify that the measurement is being taken with at least 4-hour fasting, and if possible, check for subject's hydration status.
