  • 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
