Are you serious m9, you're about to do your HSC

Reliability: Has the experiment been repeated and have the results been averaged? If not, experiment is not reliable.
Validity: Have all the variables that are not independent been kept constant? If not then experiment is not valid.
Accuracy: Has there been any errors in obtaining measurements during the experiment? If so, then there are inaccuracies.

this would have helped me last year

A biology question:

Whats the difference between reliability, validity and accuracy?

Is accuracy the same with reliability? ?

Reliability - concerned with repetition.
Validity - whether the experimental method is correct and if all variables (except for independent) has been kept constant.
Accuracy - basically use of particular equipment (instead of indicator, using a pH meter) and having minimal errors.
