Counts where rates belonged and an axis cut short at 3.0: the HS345 Unit 3 data display critique example finds both faults in one hospital's falls charts and redraws them. Searches like "hs 345 unit 3 assignment example", "hs345 unit 3 sample" and "hs345 unit 3 example" land here.
What a finished HS345 Unit 3 data display critique looks like
Each original chart is reproduced at the top of its own page with a caption quoting the report's headline. The bar chart ranks four inpatient units by raw falls over a year, placing the medical unit's 34 at the top. Below it, the critique's redrawn version divides by patient days and reorders the bars: rehabilitation leads at 6.8 falls per 1,000 patient days, behavioral health follows at 4.5, and medical drops to third at 3.6. The second original is a monthly line of the hospital-wide rate whose vertical axis starts at 3.0, so a move from 4.1 to 3.6 looks like a collapse. The redraw starts the axis at zero, adds the yearly mean of 3.8 as a center line, and shades the band monthly rates would wander through with no real change at all.
How a HS345 Unit 3 example is structured
The critique treats the two charts separately and then together. For each, the same four questions run in the same order: what the chart claims, what data it was drawn from, which design choice produces the false impression, and what an honest version shows. The bar chart's fault is the denominator. Rehabilitation holds only 14 percent of patient days yet a quarter of the falls, a pattern the raw counts bury beneath the larger medical unit. The line chart's fault is scale. On an axis cut at 3.0, a 12 percent drop erases nearly half the line's height, and in real terms it means about one fewer fall in a month of roughly seven. A closing section joins the two: the report's concern about the medical unit rests on one distortion, and its declared downward trend rests on the other.
The report's two claims, quoted
Medical is named the unit with the most falls, and falls are said to be trending down. Both sentences are reproduced exactly as the report printed them.
Falls per 1,000 patient days
A four-row table gives falls, patient days and the rate for each unit. The ranking reverses: rehabilitation's rate is about 2.6 times surgical's and 1.9 times medical's.
An axis that starts at 3.0
The redraw keeps the same twelve points on a zero-based axis. The visual drop shrinks from about 45 percent of the line's height to the 12 percent it actually was.
How far a month moves on its own
With about seven falls a month, ordinary variation spreads monthly rates across roughly 1.0 to 6.7 per 1,000 patient days. The last quarter's dip sits well inside that band.
What the committee should see instead
Rates by unit on one chart, a run chart with a center line for the trend, and counts printed beside each bar so a small unit's rate is never overread.
Where marks go in HS345 Unit 3
Critique rubrics in this course tend to reward identifying the specific design fault, explaining why it misleads, proposing a better display, and showing that display drawn. Identification credit needs precision: a paper that calls the bar chart unfair without naming the missing denominator collects little of the row. Explanation credit comes from quantifying the distortion, as the critique does with its 45 percent against 12. The proposal row rewards displays matched to the question, rates for comparison between units and a center line for change over time. Drawing the fix is where many submissions stop short, offering advice in prose instead of a redrawn chart. Graders also deduct for critiquing color or fonts while ignoring scale, for recommending a pie chart to show a rate, and for treating one low month as proof that a program worked.

HS345 Unit 3 questions, answered
Why use patient days instead of admissions as the denominator?
Because falls happen during time spent in a bed, and units differ in how long patients stay. A rehabilitation unit keeps patients for weeks, so its exposure per admission is far larger than a surgical unit's. Falls per 1,000 patient days is the denominator most hospital fall reporting uses, and the critique explains the choice in one sentence.
Is a truncated axis always wrong?
Not always. For a line tracking small changes in a measure that never approaches zero, such as body temperature, a narrower axis can be reasonable if it is clearly labeled. The problem arises when the cut exaggerates a change somebody will act on. The example argues that a fall rate sits close enough to zero that its axis should start there.
Can I critique a chart from my own hospital?
Often, yes, if the prompt allows it. Remove unit names, dates or anything that could identify patients or staff, and describe the data source in general terms. A custom sample can work from a chart you supply with identifiers stripped, and the same four questions apply to any display, from dashboards to annual reports.
