## What should a small-sample comparison show beside the headline percentage?

Use this review card before publishing a performance comparison. The aim is to show readers how much information the percentage represents, not to declare that any fixed match count proves a trend. Keep observational differences visible and avoid turning a useful arithmetic example into an unsupported forecast of the athlete’s next result.

| Planning field | Prompt or example to adapt | Your entry |
| --- | --- | --- |
| Raw counts | Write successes and opportunities together, such as four wins from five included matches. | __________ |
| One-result sensitivity | Recalculate after one additional result to show how much the small denominator can move the percentage. | __________ |
| Comparable conditions | Check style, opponent context, date range and result inclusion rules for both samples. | __________ |
| Missing observations | Identify unrecorded or excluded matches and whether they could change the comparison. | __________ |
| Next evidence | Name the additional matches or observations that would help the coach test the current interpretation. | __________ |

## Fictional examples of one additional loss

| Starting record | Starting win rate | After one loss |
| --- | --- | --- |
| 4 wins from 5 matches | 80% | 4 ÷ 6 = 66.7% |
| 40 wins from 50 matches | 80% | 40 ÷ 51 = 78.4% |
| 1 pin from 2 wins | 50% per win | 1 ÷ 3 = 33.3% after a non-pin win |

## Original fictional planning example

A fictional coach compares two reports that both show an eighty-percent win rate. One covers five matches and the other fifty. The coach writes the underlying fractions beside the rates before discussing them. The small sample contains four wins, so one additional loss changes the displayed percentage sharply. The larger sample contains forty wins, so one additional loss changes it less. The arithmetic does not establish a sudden change in ability for either athlete; it shows how the descriptive denominator affects movement.

Next, the coach checks whether the schedules and collection methods are comparable. The five-match report comes from a selected event, while the fifty-match report spans a wider period with different competition. The coach therefore avoids using the matching percentages as proof of equal strength or using their later divergence as proof that one athlete developed faster. Each sample is described on its own terms. If a coaching question needs a more relevant subset, that subset is defined explicitly rather than selected quietly to make the conclusion look stronger.

The athlete’s next task is based on the coach’s actual observations and goals, with the statistics serving as supporting context. Future records retain raw counts, sample boundaries and missing-data notes. A report can then say what changed in the evidence without making an unsupported causal story. The worksheet helps keep this process visible: define the question, show the fraction, inspect comparability and choose what to observe next. This is useful even when no sophisticated model is available. It prevents a compact percentage from carrying more certainty than the underlying matches, definitions and context can reasonably support.
