Explore how polling and collecting data can be used to strengthen your voice using the PBS KIDS series ARTHUR. When Binky doesn’t do as well as expected on a math test, he sets out to prove that the test was unfairly difficult. He polls his classmates, collects data, and presents his findings. However, Brain points out flaws in Binky’s polls—his sample size is too small, his questions lead people to respond in certain ways, and he adds his own opinions. Will Binky be able to create a reliable poll and learn once and for all how polls can be used to collect accurate data?
