# Technical writing internships: build a documentation portfolio that works

## Audit a tutorial with four task checks

Fictional practice data. The same five volunteers complete both rounds, so learning effects are possible.

### Observed task attempts, not independent people

| Measure | Before revision | After revision |
| --- | --- | --- |
| Volunteers | 5 | 5 |
| Tasks per volunteer | 4 | 4 |
| Successful attempts without help | 12 | 17 |
| Total task attempts | 20 | 20 |

## Your turn

Calculate the two observed completion rates and their percentage-point difference. Then state two reasons this does not establish a causal productivity gain.

## Your answer

[Write your approach here.]

## For your own application

Test a tutorial you actually wrote and keep the anonymous observation notes and revision history.
