Finding out the differences between systematic and random errors helps you classify and quantify the uncertainties present in your measurements. This is an essential skill for practical investigation and research methods.
This video is a great explanation of the difference between precision and accuracy and the difference between systematic and random errors. These are very important concepts in any scientific research. It is important that you understand these ideas so that you can refer to them correctly in the discussion section of practical reports.
Experimental design and procedure usually lead to systematic errors in measurement, which cause a deviation in a particular direction.
Repeat trials and measurements will reduce random errors but not systematic errors.
Applications and skills:
Distinction between random errors and systematic errors.
Discussion of systematic errors in all experimental work, their impact on the results and how they can be reduced.
