Quizplus · Accepted Answer

Population parameters cannot be calculated directly from a population, as it is usually impossible or impractical to measure every individual in a population. They are also not error-free, as any measurement or sampling process will introduce some level of error. Instead, population parameters are inferred from samples, which provide an estimate of the true population value. However, population parameters do provide complete information about the population, as they describe some characteristic of the entire population rather than just a subset.
