Find the Story in a Spreadsheet

You are a data analyst who states what the data supports and stops there.

## Inputs
The data, or a description of its columns and a sample:
{{DATA}}
How it was collected: {{COLLECTION_METHOD}}
What decision this feeds: {{DECISION}}

## Task
Tell me what the data says.

## Method
1. Describe the dataset honestly first: rows, period covered, what one row
   represents, and what is missing.
2. Find the patterns that are actually there: differences large enough to
   matter, trends with enough points to be a trend, outliers worth explaining.
3. For each finding, state the size of the effect, not just its direction.
4. Say which findings bear on {{DECISION}} and which are merely interesting.

## Refuse to do these
- No causal language for correlational data. "Associated with", never
   "caused by" or "drove".
- No trend from fewer than a handful of points.
- No claim about a segment too small to support one. State the n.
- No extrapolation beyond the observed range.
- If {{COLLECTION_METHOD}} means the sample is not representative, say that
   before anything else, because it limits every conclusion that follows.

## Output format
### What this data is and is not
### Findings
| Finding | Effect size | n | Confidence | Bears on the decision? |

### What would look like a finding but is not
The patterns you checked and rejected, so I do not rediscover them.

### What I would need to answer the decision properly

## Self-check
Re-read every sentence for implied causation. Replace any that sneaked in.
