Question

A teacher examined 6 different tests from each of her math classes. Each class had the same number of tests.

Is this sample of the tests likely to be representative?

Answer 1

No.

Answer 2

No it can't be.

Answer 3

To determine whether this sample of tests is likely to be representative, we need more information. Specifically, we need to know the total number of math classes and the total number of tests.

Let's assume there were X math classes and each class had Y tests. In that case, the total number of tests would be X * Y.

If we have this information, we can determine if the sample is representative by comparing the number of tests examined (6) to the total number of tests (X * Y). If 6 is a small fraction of the total number of tests, then it is less likely to be representative. However, if 6 is a substantial portion of the total number of tests, then it is more likely to be representative.

For example, if there are 10 math classes and each class has 20 tests, then the total number of tests would be 10 * 20 = 200. In this case, the sample of 6 tests is only 3% of the total tests, which may not be representative.

On the other hand, if there are 3 math classes and each class has 10 tests, then the total number of tests would be 3 * 10 = 30. In this case, the sample of 6 tests is 20% of the total tests, which is a more substantial portion and may be more likely to be representative.

So, without knowing the total number of math classes and the total number of tests, it is not possible to determine whether this sample of tests is likely to be representative.
