Study Notes
Types of Errors and Biases
- Random Error: Occurs when the recorded value measured by a scale or device differs from the true value, resulting in unpredictable fluctuations.
- Selection Bias: Caused by differences in the baseline characteristics of the study group, leading to skewed results.
- Bias: A systematic error in research methods that influences the results in a specific direction, affecting the accuracy of the findings.
- Self-Selection Bias: A type of bias that occurs when study participants voluntarily choose to join the study, potentially leading to an unrepresentative sample.
- Systematic Error: A type of error that occurs when the error takes place in a consistent and predictable manner, as opposed to random errors.
This quiz tests your knowledge of bias in research methods, including systematic errors that skew results in a specific direction. It covers various types of bias, such as selection bias, performance bias, detection bias, and observer bias.
