# Rank

**The `rank` command generates a ranking of results based on participant answers.**

With the `rank` command, it is possible to generate a ranking of
results based on the answers provided by participants. The command
accepts on standard input either a JSON ready for display or the
result of a filter applied to the answers that needs to be processed
through a `tengo` script to conform to the JSON schema.

## Example

Filtra le risposte date dai partecipanti al test "Math Test" e produce
una classifica dei punteggi assegnando +1 punto per ogni risposta
esatta fornita.

```
probo filter responses -i data/filters/math_test.jq | probo rank -s data/scripts/score.tengo
```
