Forbidden Words in AP Stats • Outlier (use outlier rules to prove, don’t just assume) • Skewed (too loosy-goosy, be specific: left or right) • Normal (prefer “symmetric” or “bell-shaped” – otherwise must prove via Empirical Rule) • Lurking variables (must identify a l.v. if talking about it) • Confounding (type of association; particular but over-used in wrong situations) • Range (other, better ways to describe variability) • Bias (Name the type of bias, not just “there is a bias”)
