Answer:
This type of error affects overall accuracy but does not necessarily affect precision. - Systematic error
This type of error affects precision but does not necessarily affect overall accuracy. - Random error
This type of error occurs if you use a buret that was calibrated incorrectly when it was made. - Systematic error
You can minimize this type of error by taking repeated measurements. - Random error
Explanation:
Systematic errors are errors that are attributable to instrument being used during measurement or consistent incorrect measurement during a research. They are consistently and repeatedly committed during measurements and therefore affect the overall accuracy of measurements. A person committing systematic error can have precise repeated measurement but will be far from being accurate.
Random errors on the other hand has no pattern and are usually unavoidable because they cannot be predicted. When sufficient replicate measurements are made, such errors are reduced to the barest minimum and usually do not affect the overall accuracy of measurements.
