How does random sampling contribute to research?

Random sampling significantly minimizes selection bias, which is a critical aspect of conducting valid research. When researchers utilize random sampling, each individual in the population has an equal chance of being selected for the study. This randomness helps ensure that the sample represents the broader population accurately, reducing the likelihood that the findings will be skewed due to unrepresentative samples. By minimizing selection bias, random sampling increases the generalizability of the study's results, allowing researchers to draw more reliable conclusions about the population based on their sample.

This method stands in contrast to other techniques that may result in certain groups being overrepresented or underrepresented, which can significantly impact the results and conclusions drawn from research.
