Selection bias refers to the tendency to favor certain individuals while excluding others from a study or analysis based on certain characteristics, such as age, gender, race, socioeconomic status, or other factors. This can lead to distorted or inaccurate results that do not accurately represent the population or group being studied. It is important to minimize selection bias in research and analysis by using randomization, representative sampling, and other methods to ensure that all individuals have an equal chance to participate and be included in the study or analysis.
