Supposedly, the educational district in which you teach has a statutory requirement that all learners of English know at least 90 percent of the 1000 most common words in English by the end of the sixth grade. You aren't really interested in who knows the most vocabulary, who knows the least, and so on, but rather you want to know whether all the learners in your class know at least 90 percent of the most common 1000 words. In order to acquire the result, you might extract a representative sample of 100 words from the larger list and test the students on those. You would hope that your class would all do very well on the test, scoring 90 percent or above, as evidence that they all control the required vocabulary. What kind of test is this one?
