For each of the following problems, consider how you would pose the same problem to your students. Would the wording need to change? Would you need to include more pictures? More detailed pictures? But remember we don't want to do TOO MUCH for the student. If we provide too much information, they will not need to think about what the question is asking.

Consider your problem-solving strategy for each of the following investigations. Is there another strategy that you could use? If so, which strategy would be more appropriate for understanding the concept?


Statistics is the science of collecting, classifying, and using numerical facts (data) to "tell a story" about a population or a sample from the population. The first part of the word "statistics" comes from the German word for state (stat). The word was used as a term to describe the state's practice of collecting information on births and deaths more than 300 years ago.

Examples of statistics include unemployment rate, consumer price index, rate of violent crimes, infant mortality rates, poverty rate of a country, batting average of a baseball player, free throw average of a basketball player, salary rates, and standardized test results.
