Before judging anything, the HW320 Unit 4 reference standard comparison retests two app warnings, matching each nutrient to its correct age band, edition and scope. Searches like "hw 320 unit 4 assignment example", "hw320 unit 4 sample" and "hw320 unit 4 example" land here.
What a finished HW320 Unit 4 reference standard comparison looks like
A two-part table carries the comparison. Its left half reproduces what the app reported, each nutrient as a percentage of a label Daily Value. The right half replaces those targets with the Dietary Reference Intakes for men aged 19 to 30. Magnesium is the first reversal: the app flagged 480 mg as above an upper limit, but the Tolerable Upper Intake Level of 350 mg applies only to magnesium from supplements and medications, and every milligram in this record came from beans, oats and nuts. Potassium is the second: 3,100 mg looked like two thirds of a 4,700 mg Daily Value, while the current Adequate Intake for his band is 3,400 mg. Fiber, 31 g set beside an Adequate Intake of 38 g, and sodium, 3,600 mg set beside a reduction level of 2,300, complete the table.
How a HW320 Unit 4 example is structured
The comparison usually opens by naming the person the standards must fit: age, sex, and whether pregnancy, lactation or any other adjustment applies, because every reference value is set for a band and the band decides the number. A sources paragraph cites the reference intake reports by year, including the 2019 revision that reset the potassium and sodium values. The table follows. Each nutrient then gets a short paragraph in a fixed order: the intake, the correct standard and its type, the scope of that standard, and what the comparison supports. Types matter here, since an Adequate Intake, a Recommended Dietary Allowance and an upper level permit different conclusions. The app's defaults get a paragraph of their own explaining why label values gave misleading targets for one man. The conclusion lists exactly what changed when the standards did.
The band before the number
Men aged 19 to 30 have a magnesium allowance of 400 mg, men from 31 upward 420 mg. The comparison names the band first, because a single birthday can move the target.
An upper level with a narrow scope
The magnesium ceiling covers supplemental forms only, since food magnesium has not been linked to the effects that set it. Reading the scope line of the reference report is what reverses the app's warning.
Current edition, current figure
Potassium's Adequate Intake was revised in 2019. The comparison sets the older figure the app relied on beside the current one and cites both, so the change is visible rather than silent.
The verb each standard permits
An Adequate Intake supports only a soft conclusion, so the potassium shortfall is called uncertain; the sodium figure, a level to stay under, supports a firmer one. Each finding uses only the wording its standard allows.
Defaults named, then replaced
The app's reliance on label Daily Values is explained in one paragraph and set aside. Those values exist so packages can be compared with each other, and judging one man's intake is a different task.
Where marks go in HW320 Unit 4
Most lost marks trace to the wrong standard, usually a label Daily Value or a figure for the wrong age or sex band, which quietly corrupts every conclusion that follows. Scope errors come next and are harder to see: an upper level applied to food when the reference limits it to supplements, or a sodium figure described as a requirement rather than a level to stay under. Comparisons also slip when they use a superseded edition, and potassium is where that happens most often in this course. Treating every standard as a pass-or-fail line costs accuracy credit, since falling short of an Adequate Intake leaves adequacy unknown rather than disproved. Tables without sources or years draw comments. Finally, prescribing foods to close each gap turns a comparison into individual advice, which loses marks in many sections.

HW320 Unit 4 questions, answered
Which reference values should the comparison use?
The Dietary Reference Intakes for the person's exact age and sex band, taken from the most recent report for each nutrient, unless your prompt names another standard. Avoid comparing an individual against label Daily Values, since those were set to cover most people at once and serve packages rather than persons. Name the report and year for every nutrient in the table.
Why does the upper limit for magnesium not apply to food?
The reference report set that limit from effects seen with supplemental and medicinal magnesium, and food sources have not been shown to cause them. A few other upper levels, including those for folic acid and niacin, are likewise limited to certain forms. Reading the scope statement in the report, not only the number, is what keeps a comparison from flagging a perfectly ordinary pattern.
What if my record was analyzed with software that uses outdated values?
Report what the software printed, then redo the comparison against the current values and show both. Graders usually reward noticing the discrepancy more than they penalize the software. State the edition each figure comes from, and if the prompt requires the course's own program, use it while noting any value that has since been revised.
