Q. A teacher examined 22 different tests from each of her math classes. Each class had the same number of tests.\newlineIs this sample of the tests likely to be biased?\newlineChoices:\newline(A)yes\newline(B)no
  1. Understand scenario: Step 11: Understand the scenario and what is being asked.\newlineThe teacher took 22 tests from each of her math classes, and each class had the same number of tests. We need to determine if this sampling method is likely to be biased.
  2. Analyze sampling method: Step 22: Analyze the method of sampling.\newlineSince the teacher took the same number of tests from each class, the sampling method seems uniform across all classes. This suggests that there is no preference or exclusion of any particular class.
  3. Consider bias definition: Step 33: Consider the definition of bias in sampling. Bias in sampling occurs when certain members or groups within the population are favored or ignored. In this case, since every class is treated equally and the same number of tests is taken from each, there is no indication of favoritism or avoidance.
