Questions and Answers

Which type of bias occurs when participants select themselves to join the study?

  • Observer bias
  • Performance bias
  • Self-selection bias (correct)
  • Attrition bias

    • What is the primary concern when examining the risk of selection bias?

  • Allocation concealment (correct)
  • Detection bias
  • Zero-time Bias
  • Reporting bias

    • What is the main characteristic of selection bias?

  • Occurs when the error takes care in a systematic manner
  • Occurs when the recorded value measured by the scale is different from the true value
  • Caused by differences in the baseline characteristics of the study group (correct)
  • Occurs when participants select themselves to join the study

    • Which type of bias occurs when differences in baseline characteristics of the study group lead to skewed results?

    Study Notes

    • Bias: Systematic error in research methods that influences results in a specific direction
    • Selection Bias: Caused by differences in baseline characteristics of study groups due to weak sequence generation or allocation methods
    • To minimize selection bias: Review methods of random sequence generation and allocation concealment
    • Self-selection Bias: Occurs when participants choose to join studies, resulting in non-representative samples
    • Mobile Photography: MDP (Mirrorless Digital Camera) advantages over DSLR (Digital Single-Lens Reflex)
    • MDP advantages: Cost-effective, lighter, faster learning curve, continuous light, easier disinfection
    • Picture quality factors: Sensor size, pixel size, aperture
    • Larger sensor: More competent cameras with larger pixels and ability to capture more light
    • Pixel size: More megapixels equals more image detail, a minimum of 12 MP required for high-quality MDP photos
    • Aperture: Controls the quantity of light that reaches the sensor, important for optimal image quality. Some camera apps allow adjustment.
