What a partial answer often does
It says repeated trials improve reliability, but does not explain consistency or the effect on confidence in the results.
Investigating Science marked response
HSC Investigating Science sample marked response: apply the term, then explain the evidence.
See a HSC Investigating Science sample marked response showing how to apply validity, reliability or accuracy to a scenario.
Independent. Not official HSC/NESA.
The missing marking point
The answer needs to connect repeated trials with consistency of results and reduced influence of random variation.
The rewrite move
Define the term only briefly, then spend the rest of the answer applying it to the method and evidence.
