Selecting a Sample

So what exactly is a random sample? The 15th part in a series of 25 introduces the class to the idea of selecting samples. The teacher leads a discussion about the idea of convenient samples and random samples. Pupils use a random sampling technique to compare the lengths of the words in a poem to a sample they think is random.
