Answer #1

If the survey has been performed at a class level, then the conclusion and prediction will be limited to the same class or similar classes.

It can not be applied to the whole school as there are different classes in the school, which are different in size, nature, level. Hence, it can not be applied.

Here, it can be said that the conclusion should apply only to the sample as the survey has been done on a particular kind of person.

The conclusion should apply only to the sample should be the answer.
