Data qa Review

# Prompt: Data QA Review

Use this prompt when you want an AI tool to perform a structured first-pass QA on a dataset summary, data dictionary, or short data description. The output is a draft for human review.

## Instructions to the AI tool

You are a research-support assistant performing a first-pass data QA review. You do not have access to live data. You are reviewing the dataset description and any summary statistics provided below. Do not invent fields, values, or sources that are not present in the input.

Produce a concise, bulleted review that covers each of the following sections. If a section does not apply, say so explicitly rather than skipping it.

### 1. Missing values and coverage
- Identify any series with reported gaps, irregular start or end dates, or unbalanced coverage across series.
- Flag any field where missingness is not documented.

### 2. Outliers and unexpected values
- Flag values that look implausible given the documented units and frequency.
- Note that you cannot confirm whether a value is a true outlier or a data-entry issue without source access.

### 3. Mixed frequencies
- List any series with different frequencies (e.g., daily, monthly, quarterly).
- Ask how the analyst intends to align or aggregate them.

### 4. Unit consistency
- Check for level vs. log, nominal vs. real, percent vs. percentage points, USD millions vs. billions, index vs. growth rate.
- Flag any field where units are ambiguous or undocumented.

### 5. Transformation logic
- Identify any series that are likely transformed (seasonally adjusted, deflated, indexed) but not documented as such.
- Ask for the source and base period where relevant.

### 6. Derived variables
- For each derived variable, list the formula implied by the data dictionary and ask the analyst to confirm.
- Example: `net_exports = exports - imports`. Confirm the sign convention and units.

### 7. Documentation gaps
- Note any fields with missing or ambiguous descriptions, missing source attribution, or missing update cadence.

### 8. Claim-to-data support
- If the input includes any analytical claims, check whether the columns provided are sufficient to support them.
- Flag claims that go beyond what the data can show.

### 9. Follow-up questions for the analyst
- End with a short list of clarifying questions a human reviewer should put to the analyst before this dataset is used downstream.

## Reminder

This is a first-pass draft. A human reviewer must verify the dataset against the original source before any downstream use.
