Learning objectives (3)
Juniper's sample centers are lower in Year 2. That sentence is supported. “The new credit policy caused collections to improve” is not.
The gap between those statements is where professional judgment begins.
Use a claim ladder
| Claim type | What Juniper supports now | What remains missing |
|---|---|---|
| Sample description | Year 2 mean is 2.5 days lower; median is 5 days lower; spread is much larger | Nothing beyond the selected values |
| Population estimation | Separate one-sample mean intervals can be mechanically computed | Stronger condition, dependence, and frame evidence; an appropriate method for comparing years |
| Association | The year labels accompany different sample distributions | Control of mix, terms, open invoices, customer composition, and other period changes |
| Cause | Not established | Causal design, policy timing, implementation, confounders, mechanisms, and rival evidence |
| Forecast or risk | Not established | Future population, stability, loss definition, model, horizon, and validation |
| Decision | Not established | Objectives, costs, constraints, consequences, authority, and alternatives |
Do not jump rungs because the audience wants an answer quickly.
Give accounting and finance readers different deliverables
The accounting-control note should reproduce the source query and cutoff, reconcile frame counts and amounts, test unique keys, trace the 78-day invoice, verify issue and final-application dates, inspect exclusions and unsettled invoices, and preserve the analysis file.
The finance memo should state the target and sample, show center and spread, report the interval method and conditions, distinguish historical observation from population and future claims, name competing explanations, and request evidence. It should not smuggle a policy recommendation into a descriptive sentence.
Name the next evidence
Useful requests are specific:
- invoice-level issue, due, payment, final-application, dispute, adjustment, write-off, and customer keys;
- the complete frame query and record/amount reconciliation;
- aging and open-invoice populations at both year-ends;
- credit-term and policy changes with effective dates;
- customer and product mix, repeated-customer concentration, and seasonality;
- subsequent collections and documented causes for late settlement; and
- a prespecified two-period comparison design if the population difference is the decision target.
“More data” is not a control objective.
Open the worked conclusion, then complete the inference-boundary item.
Exit check
Write one paragraph with four labeled clauses: supported observation, conditional estimate, unsupported claim, and next evidence. If a reader can mistake a sample statistic for a forecast or a year label for a cause, revise the clause.
