True or False: Randomness in sampling is crucial for representativeness.

Randomness in sampling is indeed crucial for representativeness because it helps to ensure that every individual in the population has an equal chance of being selected. This reduces selection bias, which can skew results and lead to inaccurate conclusions about the entire population. When a sample is drawn randomly, it is more likely to reflect the diverse characteristics of the larger group, allowing for generalizations that can be made with greater confidence.

In contrast, non-random sampling techniques can lead to a sample that may not accurately represent the targeted population, making it difficult to draw valid conclusions. Random sampling provides a scientific basis for conducting analyses and enhances the validity of the findings. As a result, when conducting research, particularly within the healthcare sector where compliance to regulations and guidelines is critical, maintaining randomness in sampling is essential for obtaining reliable and actionable data.
