This report analyzes the TidyTuesday 2021-03-16 release on Video Games — 83,631 rows after cleaning and merge. Did critical acclaim correlate with commercial success in this slice of gaming history?
Five charts track Avg across time, category, and named entities — trend, leaders, distribution, tiers, and relationships. Where companion files exist in the repo, they are joined before analysis so reception, geography, or metadata columns are not left on the table.
FAST FACTS
DATASET CONTEXT
The source is the TidyTuesday release from 2021-03-16 (R for Data Science community). This working file contains 83,631 rows and 8 columns after merging all available CSV/XLSX tables in the week folder.
Charts are exported as Plotly JSON with PNG fallbacks. Medians are used for robustness where distributions skew. Index-style fields (row numbers, sequential IDs) are excluded from metric selection.
How to read this report: start with the chart caption, then ask what the metric actually means, what a non-expert should notice first, and what an expert would challenge in the source. The goal is not to memorize every number; it is to leave with a sharper question than the one you arrived with.
Reader path: if you are new to the topic, treat each chart as a guided tour of one question: who leads, how concentrated the field is, what changes over time, and where the outliers sit. If you already know the domain, use the same charts as a challenge: check whether the metric is the right proxy, whether the source omits an important population, and whether the headline survives the limitations section.
CHART 1 — TREND
Median avg is rising from 212 in the opening period to 309 at the close.
Annual medians filter one-off spikes so the structural slope — not viral outliers — drives the story.
CHART 2 — LEADERS
Dota 2 leads at 475,924 — 64,656 marks the median among the top dozen.
Head-of-field concentration is where quality, scale, or brand visibly separates from the pack.
CHART 3 — DISTRIBUTION
Category boxes reveal whether avg consensus is shared or contested across tiers.
Wide whiskers flag segments where outliers — not averages — drive reputation.
CHART 4 — GAP ANALYSIS
January sits 36.9 above the median; October trails by 23.3.
Diverging from the median exposes which tiers over- or under-perform — not just who ranks first.
SUPPLEMENT — RELATIONSHIP
Joint plot of avg and gain surfaces clusters the averages erase.
Bubble size tracks repeat presence — outliers are archetypes, not noise.
LIMITATIONS
Community-cleaned TidyTuesday snapshots are not live APIs. Missing values, spelling variants, and week-of-export coverage limits apply. Merged tables may fan out or duplicate rows when join keys are imperfect.
Findings describe the file on hand — treat them as structural signals about Video Games, not exhaustive truth about the full domain.
CONCLUSION
Read as a teaching map, Video Games shows why one metric is rarely enough: leaders, tails, trends, and relationships each answer a different question about avg.
The best reading is modest: use the chart to sharpen the question, then check the source and limits before turning it into a claim.
