Perhaps how to perform a titration, and what happens to the calculated value of acid/base if errors occur in the method (like using deionised water to rinse burette)
this means that the calculated value is lower than should be right

Depends on what the error is & where it occurred. For rinsing the burette with deionised water, the titrant we place in there will be diluted, thus it will have a lower concentration than expected. Thus, more of it will be required to neutralise the titrand, resulting in the tiratnd's calculated concentration being higher than in reality.
