Figures

3/10

Five plt.title(...) calls outside any exercise/solution context (lines 395, 414, 425, 482, 618) — repeated qe-fig-003 violation. One static {figure} (line 246, Venn diagram) lacks name:.

References

N/A

No citations.

Links

10/10

Uses {doc}`earlier lecture on pandas <pandas>` correctly per qe-link-001.

Admonitions

9/10

Two {exercise-start} / {solution-start} pairs gated; :class: dropdown and :label: correct per qe-admon-001/qe-admon-002/qe-admon-005; one {hint} admonition; one {note} admonition.

Issues#

Critical#

None found.

High severity#

  • [qe-fig-003] — Five plt.title(...) calls embed titles in matplotlib figures outside exercise/solution context. Examples: line 395 plt.title('Average real minimum wage 2006 - 2016'), line 414 plt.title('Average real minimum wage'), line 425 plt.title('Average real minimum wage'), line 482 plt.title('Real minimum wages in 2015'), line 618 plt.title('Employment in Europe (2015)') (inside solution — exempt). Of these, four are in main-body code cells and are clear violations; line 618 is inside a solution and exempt per qe-fig-003. Count: 4 clear violations.

Medium severity#

  • [qe-writing-006] — Section headings use Title Case rather than sentence case. Examples: line 72 ## Slicing and Reshaping Data, line 187 ## Merging Dataframes and Filling NaNs, line 352 ## Grouping and Summarizing Data, line 488 ## Final Remarks, line 497 ## Exercises. Count: 5 occurrences.

Low severity#

  • [qe-fig-005] — The static {figure} at line 246 (Venn diagram) and the embedded plt.* plots lack name: metadata.

  • [qe-fig-006] — plt.xlabel('Country'), plt.xlabel('Year'), plt.ylabel('2015 USD'), plt.ylabel('Percentage of population (%)') use Title Case (lines 379, 397, 396, 617). “Country” / “Year” should be lowercase per qe-fig-006; “USD” is a proper-noun acronym (acceptable).

Strengths#

  • Lecture title uses {index} role with Title Case per qe-writing-006.

  • One-sentence paragraphs and clean lists.

  • Non-Anaconda seaborn correctly installed at top with hide-output per qe-code-003.

  • Good use of {doc} cross-references per qe-link-001.

  • Exercise/solution pairs use full gated/dropdown/label compliance.
