- 5.2 Meet the course dataset FLUID-ICU (live R cleaning demo)
- 5.3 Describing and showing data: summaries, figures, tables
- 5.4 Describe the course dataset: Table 1 and figures
- Proposal builder 5: variables, mini-CRF, data dictionary, data management
Timetable
| Start | Clock* | Min | Segment |
|---|---|---|---|
| 0:00 | 19:30 | 10 | Recap quiz |
| 0:10 | 19:40 | 35 | 5.1 Good data by design: variable types, CRF principles, data dictionary, validation, data management (EDC, double entry, audit trail, backups), preventing missing data; whole-class task: fix the CRF items |
| 0:45 | 20:15 | 25 | 5.2 [DS] Meet the course dataset: the FLUID-ICU study, raw vs clean data, the data-quality problems found, live R demo of cleaning and the cleaning log; the five questions Q1 to Q5 introduced (each participant chooses one for their manuscript by the end of Session 6) |
| 1:10 | 20:40 | 15 | BREAK |
| 1:25 | 20:55 | 35 | 5.3 Describing and showing data: mean/median, SD/IQR, shapes, which graph for which data, good vs bad figures, publication-quality tables, Table 1 |
| 2:00 | 21:30 | 25 | 5.4 [DS] Describe the course dataset: live demo of Table 1 and figures; the class reads the FLUID-ICU Table 1 and figures together |
| 2:25 | 21:55 | 30 | Proposal builder 5: modelled live (variables table, mini-CRF, data dictionary rows, data-management plan); each participant drafts their own variables table (finished as homework) |
| 2:55 | 22:25 | 5 | Wrap-up |
*Times are relative to the start of the session; the clock column shows Vietnam time for the online 19:30–22:30 session. All exercises are done by the whole class together (no groups). [DS] = course-dataset content (FLUID-ICU analysis and manuscript writing).

Before this session
- Proposal Part 2 finished.
- Have a first look at the course dataset page: what FLUID-ICU is and its data dictionary.
After this session (homework)
- Your proposal: start Proposal Part 3 (variables table, mini-CRF, data-management plan).
- Look at the five results packs (Q1 to Q5) on the Course dataset page. You will choose one for your manuscript by the end of Session 6.
- Exercises 3–5 on the Session 5 sheet (choose the right summary, judge a bad figure, spot the problems in the raw FLUID-ICU data).
