A Level Physics: How to improve accuracy and precision? Random and systematic errors.

Random and systematic errors and graphs.
Which one affects the gradient and which one the intercept?
How do we improve accuracy and precision?

If there is a systematic error in an experiment, it will shift all the data points by the same amount so repeated and averaged data (RAD) will also be shifted so RAD will not get you closer to the true value so it will not improve accuracy. Rather RAD will average out random errors and improve precision
