Systematic errors shift all readings in one direction and affect accuracy, whereas random errors cause scatter about a mean and affect precision. Systematic errors can be reduced by taking the average of multiple repeated readings, whereas random errors cannot. Systematic errors affect the precision of measurements, while random errors affect the accuracy. Systematic errors arise from unpredictable environmental fluctuations, whereas random errors arise from miscalibrated instruments.
