Triplicate readings, a stated protocol for each site, and error reported next to every mean distinguish this NS310 Unit 4 anthropometric measurement set, taken on one composite volunteer. Searches like "ns 310 unit 4 assignment example", "ns310 unit 4 sample" and "ns310 unit 4 example" land here.
What a finished NS310 Unit 4 anthropometric measurement set looks like
A protocol table comes first: for each measurement, the instrument, its resolution, the landmark and the posture, from a wall-mounted stadiometer read to 0.1 cm to a Lange caliper read to the nearest millimeter at the midpoint of the back of the upper arm. The data table follows, three trials per site with the mean and the range, all bracketed: height [176.4], [176.6], [176.5] cm; waist at the top of the iliac crest [98.0], [98.6], [97.8] cm; triceps skinfold [14], [16], [15] mm. Hip circumference at its widest point and mid-upper arm circumference [32.4] cm are reported the same way. A derived-values section gives BMI [27.1], waist-to-hip ratio [0.94] and arm muscle circumference with its formula shown. A reference comparison and an error section complete the set.
How a NS310 Unit 4 example is structured
Protocol precedes data because a number cannot be judged without knowing how it was taken. Two waist readings taken at different landmarks are different measurements, and the set names the published protocol it follows, the NIH iliac crest method rather than the WHO midpoint. Triplicate trials are reported in full instead of as means alone, so the reader sees that height repeats within 2 mm while the skinfold varies by 2 mm on a reading of about 15, a far larger relative error. Derived values follow with formulas, and precision is carried through honestly: BMI to one decimal, never three. Reference comparison uses cut-points matched to the volunteer's sex and age, with their sources. The last section explains what the numbers cannot show: BMI does not separate fat from muscle, and one skinfold site is a weak guide to total body fat.
Landmarks named before numbers
Each site is defined anatomically, the acromion and olecranon for the arm midpoint, the top of the right iliac crest for the waist, so another measurer could repeat the reading on another day.
Three trials, all shown
Means sit beside ranges for every site. Showing all three readings lets a grader see which measurements were stable and which were not, instead of trusting a single tidy figure.
Precision the instruments allow
The scale reads to 0.1 kg and the Lange caliper to 1 mm, and every reported value respects those limits. Derived values carry one decimal place and no more.
Cut-points with their sources
BMI against WHO adult categories, waist against the NIH threshold for men, waist-to-hip ratio against the WHO expert consultation figure. Each comparison names the population its cut-point was built for.
Limits of tape and caliper
The volunteer lifts weights three times a week, so a BMI in the overweight range may reflect muscle as much as fat. The set says so and names body composition methods that could separate the two.
Where marks go in NS310 Unit 4
Measurement sets are commonly graded on technique, accuracy of calculation, appropriate reference comparison and interpretation of error. Technique marks depend on the protocol table: named instruments, resolutions, landmarks and repeated trials. Calculation marks require BMI, waist-to-hip ratio and arm muscle circumference computed correctly with the formulas visible. Reference marks go to cut-points appropriate to the person's sex and age, cited to their source, rather than a single chart applied to everyone. Error interpretation is where the example gains most, comparing the relative variability of the skinfold with that of height and stating what the difference means for confidence. Deductions typically follow from single readings, values quoted to more decimals than the instrument reads, a waist measured at an unnamed site, and a BMI category presented as a verdict on health.

NS310 Unit 4 questions, answered
What if I do not have a skinfold caliper?
Many sections make skinfolds optional for exactly that reason, or accept an inexpensive plastic caliper with its limits stated. Circumferences need only a non-stretch tape. Where a measurement cannot be taken properly, it is better to omit it and explain why than to report a reading from improvised equipment, which graders tend to question closely.
Should the waist be measured at the navel?
Use a published landmark and name it. The NIH protocol places the tape at the top of the iliac crest, while the WHO protocol uses the midpoint between the lowest rib and the iliac crest. The navel is convenient but shifts with body shape, so most courses prefer an anatomical site, and the cut-points applied should match the protocol used.
How should measurement error be reported?
At minimum, give every repeated reading and its range. Many courses introduce the technical error of measurement, calculated from repeated trials, and a relative version expressed as a percentage of the mean, which makes different sites comparable. The example uses the range and a relative figure to show why a skinfold deserves less confidence than a height.
