How do random errors arise?
Random errors arise from unpredictable fluctuations in an instrument’s readings due to uncontrollable factors, affecting the precision of measurements.
How do systematic errors arise?
Systematic errors arise from faulty instruments or flaws in the experimental method, affecting the accuracy of measurements.
What is a zero error?
A zero error is a type of systematic error that occurs when an instrument gives a reading when the true reading is zero.

How can random errors be reduced?
Random errors can be reduced by
repeating measurements several times and calculating an average
using a device with smaller measuring intervals
How can systematic errors be reduced?
Systematic errors can be reduced by
recalibrating instruments or using different instruments
making corrections or adjustments to the technique
