| Variant | Impressions | Clicks | Inquiries | Title |

| B | 800 | 48 | 8 | Question title / Título pregunta |
1. Justify objective, segment and channel
FEP1 supplies eight fictional notes: six ask for catalog clarity, two for scheduling. Not unique people or representative research. FEP2 authorizes local catalog-information prototypes only. Fictional stationery has no confirmed prices, stock or delivery.
Hypothetical objective: test whether a title helps locate catalog information and formulate a relevant inquiry, not sales or guaranteed customers. Proposed segment: people voluntarily selecting that category in a future authorized test. Infer no age, wealth, sensitive attributes or identity.
Proposed channel: a local page mockup supports title comparison without advertising accounts or sends. No email/message permission is supplied. Activity: document objective/segment/channel, evidence and one unknown for each.
Worked feedback
Feedback: six notes support clarity exploration, not market size or purchase intent. A local mockup is a laboratory-feasibility choice, not universally best channel. A sales objective needs absent evidence/authority. Outcome 1: three justified, bounded decisions.
2. Design A/B protocol and suspension
Variants keep the same fictional body and change one title: A“Explore the stationery catalog”;B“Which product do you need to ask about?” Future testing needs authorized assignment/measurement, consistent purpose and definitions. This exercise performs no assignment and aggregate totals establish no causality.
Propose only variant ID, impression/click/inquiry counts and period, no names, email, IP or sensitive data. Verify permission/purpose before collection. Without permission, retain a local plan instead of collecting. Seek no consent through unauthorized outreach.
Exercise checkpoint: review at 1000 impressions per variant, not statistically sufficient sample size or a calendar. Suspend planned collection for absent/withdrawn permission, sensitive data, incompatible definitions or checkpoint reached. Activity: state hypothesis, single variable, allowed fields and safe outcomes.
Worked feedback
Feedback: this is an A/B plan, not a launched advertisement. FEP3 documents no randomization or equivalent exposure. A checkpoint triggers review, not automatic winner selection. Outcome 2: explicit protocol/suspension, no spending or providers.
3. Interpret three ratios, not one overall winner
FEP3 gives fictional period W-TEST: A 1000 impressions,50 clicks,10 inquiries;B 800 impressions,48 clicks,8 inquiries. Aggregate events, not unique people or linked individual journeys. No sales, payments, costs or revenue.
Clicks/impressions: A 5%, B 6%. Inquiries/clicks: A 20%, B≈16.7%. Inquiries/impressions: A 1%, B 1%. Higher click/impression ratio accompanies lower inquiry/click ratio. Different questions/bases establish neither overall winner nor profitability.
Activity: calculate six fractions/percentages with period and units. Write two observations and three limits. Cost/inquiry may only be symbolic cA/10 and cB/8 if fictional costs were supplied;assign no budget or ROI without relevant cost/revenue.
Worked feedback
Feedback: these ratios establish no return, actual cost or causal effect. Distinct impressions do not prove distinct people. Bhas not reached 1000 checkpoint, which is administrative rather than inferential. Outcome 3: six correct bounded calculations, no spending decision.
4. Test errors and deliver a reversible proposal
Separate variants:VE1 sets Bimpressions to zero with clicks retained;VE2 permission unconfirmed;VE3 sensitive field appears;VE4 inquiry definitions incompatible. VE1 blocks that ratio and needs source review;VE2–VE4 suspend collection/comparison plans. Change no figures to force attractive results.
Deliver decision sheet, A/B protocol, metrics and suspension matrix. Preserve original/versioned corrections. Sources are only the fictional notes/counts, not connected ad platforms. No function creates an advertisement or spends a budget.
Activity: walk through variants and self-inspect evidence, protocol, arithmetic and limits 0–2 for editorial guidance. Explain missing evidence for statistical inference. Transfer no free-policy threshold or PRO grade.
Worked feedback
Feedback: zero denominator→not calculable, not automatic 0%;unknown permission→suspend;sensitive data→suspend without copying;incompatible definitions→suspend comparison. No completed human support, PROcalendar, enrollment, statement, benefit or promised revenue.
