Study Notes
Random Errors
- Random errors occur due to incorrect timing or instrument reading by the person conducting the measurement.
- Examples of random errors include:
- Difficulty in reading the scale of a measuring cylinder when measuring small volumes (e.g., 25 cm3 of hydrochloric acid).
- Incorrect reading of the scale by the person conducting the measurement.
- Fluctuations in environmental factors, such as temperature, which can affect the results of the investigation.
- Random errors can either increase or decrease the result, and can be reduced by repeating the experiment and calculating a mean for the set of data.
Systematic Errors
- Systematic errors occur due to a faulty or poorly designed experimental method.
- Examples of systematic errors include:
- Errors resulting from a poorly designed experimental method, as shown in the student's investigation.
- Other potential systematic errors that can occur in the investigation.
