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.
