Define the columns
State that units are sample counts and the table is fictional. Define which rows the check covers.
Concrete output: A data-dictionary note.
FICTIONAL LEARNING EXERCISE
A fictional stock-movement review
Review opening, incoming and outgoing values in a simple table. Do not make real inventory or ordering decisions.
Inspect the sample file
8 sample rows · 5 columns
| item_id | opening_units | incoming_units | outgoing_units | recorded_closing_units |
|---|---|---|---|---|
| A01 | 20 | 5 | 7 | 18 |
| A02 | 15 | 4 | 3 | 16 |
| A03 | 30 | 0 | 8 | 22 |
| A04 | 12 | 6 | 2 | 16 |
The table shows the first four rows. The file is fictional; some exercises intentionally include missing or conflicting values. Do not interpret them as real operational outcomes.
Download fictional sample CSV ↓Run the simple calculation
Compare opening plus incoming minus outgoing with recorded closing. Flag discrepancies as data questions.
Concrete output: A small table with a check column.
Separate missing information
For missing values or explanations, write what record would confirm them instead of assuming a real loss.
Concrete output: Two verification questions.
Prepare a summary
Explain the discrepancy, calculation and decision limits on one page.
Concrete output: An exercise review report.
My own project narrative
Write what you actually did and its limits in your own words rather than copying a prewritten achievement.
Ask yourself before saving
- Did I state the sample unit?
- Did I confuse missing data with a loss conclusion?
- Does the result incorrectly look like a real ordering decision?
