What a finished product looks like

This is a model of the work you should turn in today. Use it to check your own: match the structure and the level of detail, do not copy it. Your data and wording should be your own.

Outbreak line list with incidence and prevalence
Completes: Completes the Problem 5 line-list step: a case-by-case line list with key fields plus calculated incidence and prevalence and a trend observation.

Line list (one row per case), gastrointestinal outbreak:

  • Case 1: onset day 1, symptoms vomiting/diarrhea, outcome recovered
  • Case 2: onset day 1, symptoms diarrhea, outcome recovered
  • Case 3: onset day 2, symptoms vomiting, outcome still sick
  • Case 4: onset day 3, symptoms diarrhea/fever, outcome still sick
  • Case 5: onset day 4, symptoms vomiting, outcome still sick

Incidence (new cases) by day: day 1 = 2, day 2 = 1, day 3 = 1, day 4 = 1.

Prevalence on day 4 (all still sick on day 4): 3 cases (cases 3, 4, 5).

Trend observation: New cases appeared every day through day 4, so the outbreak was still ongoing and had not yet peaked.

Why this matters

This model shows the level of evidence and organization needed to complete: Completes the Problem 5 line-list step: a case-by-case line list with key fields plus calculated incidence and prevalence and a trend observation.

Build yours step by step
  1. Name the variables and include units.
  2. Enter observations without changing the raw values.
  3. Check labels, calculations, and patterns before interpreting the data.
Change it for a new task

Keep the structure. Replace the question, facts, measurements, and evidence. Then recheck units, vocabulary, and whether the conclusion goes beyond the evidence.

Claim ceiling: Today's evidence supports a classroom claim about line list. It cannot prove causation, diagnose a real patient, or justify action outside this room.

WebXam problem for today's skill

One exam-style question that uses exactly what you practiced today. Try it before you reveal the answer, then read why each choice is right or wrong.

WebXam-style domain: Microbiology Testing and TechnologySelf-check skill: Calculating prevalence from a line list
A line list shows 5 total cases. On day 4, cases 1 and 2 have recovered and cases 3, 4, and 5 are still sick. What is the prevalence (active cases) on day 4?

Tap an answer to see the full explanation. Nothing is recorded or graded.

Why this practice matters

It builds this reusable test skill: Calculating prevalence from a line list.

Use it on a new WebXam question
  1. Name the concept or data pattern being tested.
  2. Cross out choices that violate that rule or the evidence.
  3. Justify the best remaining choice before checking the answer.
