Question

Dale surveyed 7 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

Answer 1

## Step 1The problem is about the concept of bias in sampling. Bias in sampling refers to a situation where the sample selected does not accurately represent the population from which it is drawn. This can happen when the sample is not randomly selected or when the sample is not representative of the population.## Step 2In this case, Dale surveyed 7 teachers from each academic department at school. The problem does not specify whether the number of teachers in each department is equal. If the number of teachers in each department is not equal, then the sample may not be representative of the entire population of teachers.## Step 3However, if the number of teachers in each department is equal, then the sample is likely to be unbiased because each department is equally represented in the sample.
