- Identify biased samples (A1-MM.1)
AI.DS.3 Use technology to find a linear function that models a relationship between two quantitative variables to make predictions, and interpret the slope and y-intercept. Using technology, compute and interpret the correlation coefficient.
AI.DS.4 Describe the differences between correlation and causation.

AI.QE.4 Solve quadratic equations in one variable by inspection (e.g., for x² = 49), finding square roots, using the quadratic formula, and factoring, as appropriate to the initial form of the equation.
AI.QE.5 Represent real-world problems using quadratic equations in one or two variables and solve such problems with technology. Interpret the solution(s) and determine whether they are reasonable.
- Solve quadratic equations: word problems (A1-CC.)
AI.QE.6 Graph exponential and quadratic functions with and without technology. Identify and describe key features, such as zeros, lines of symmetry, and extreme values in real-world and other mathematical problems involving quadratic functions with and without technology; interpret the results in the real-world contexts.
