1. Recognizes a statistical question as one that anticipates variability in the data related to the question and accounts for it in the answers
A statistical question is framed in such a way that the data collected is expected to vary. The essence of statistics is to study patterns in data, so any good statistical question will not be answered by a single fixed value. Instead, it requires collecting data, summarizing it, and interpreting the results in terms of variability.
For example, the question “How tall is Michael Jordan?” is not a statistical question because there is only one answer. On the other hand, “What are the average heights of seventh-grade students in a middle school?” is statistical because the height of each student will vary, and the variability itself must be accounted for when calculating averages and other measures.
