Gather random samples and use them to make inferences about the percentage of blue candies in a jar in this interactive from MPT. In the accompanying classroom activity, students use the interactive and then use random sampling to explore a question involving hands-on materials in the classroom. They compare results from different samples and then make appropriate inferences. To get the most from the lesson, students should be comfortable expressing a fraction as a percentage and be familiar with the notion of a random sample. For a longer self-paced student tutorial using this media, see "Simple Random Sampling" on *Thinkport* from Maryland Public Television.
