MI. 11 Identify representative, random, and biased samples csp
Hazel surveyed 2 teachers from each academic department at school. Each department has
an equal number of teachers.
Is this sample of the teachers in the school likely to be biased?
yes no

Using equal representation from each department may lead to a biased sample if the goal is to generalize opinions about the entire teaching staff. Since each department is likely to have different sizes of remaining teachers, sampling two teachers from each may not accurately reflect the overall population.

To avoid bias, random selection of teachers from the entire pool, instead of department-based quotas, could result in a more accurate representation of the entire teaching staff’s opinions and concerns. This approach allows for more diverse perspectives to emerge, ensuring that smaller departments do not have an outsized influence on the survey results.
