AII.DSP Data Analysis, Statistics, and Probability

AII.DSP.1 Distinguish between random and non-random sampling methods, identify possible sources of bias in sampling, describe how such bias can be controlled and reduced, evaluate the characteristics of a good survey and well-designed experiment, design simple experiments or investigations to collect data to answer questions of interest, and make inferences from sample results.
- Identify biased samples (A2-FF.1)
AII.DSP.2 Interpret and compare univariate data using measures of center (mean and median) and spread (range, interquartile range, standard deviation, and variance). Understand the effects of outliers on the statistical summary of the data.
AII.DSP.3 Use technology to find a linear, quadratic, or exponential function that models a relationship for a bivariate data set to make predictions; Interpret the correlation coefficient for linear models.
AII.DSP.4 Using the results of a simulation, decide if a specified model is consistent to those results. Construct a theoretical model and apply the law of large numbers to show the relationship between the two models.
- Analyze the results of an experiment using simulations (A2-FF.13)
AII.DSP.5 Understand dependent and independent events, and conditional probability; apply these concepts to calculate probabilities.
AII.DSP.6 Understand the Fundamental Counting Principle, permutations, and combinations; apply these concepts to calculate probabilities.

AII.ASE Arithmetic and Structure of Expressions

AII.ASE.1 Explain how extending the properties of integer exponents to rational numbers allows for a notation for radicals in terms of rational exponents (e.g. 5^(1/3)) is defined to be the cube root of 5 because we want (5^(1/3))^3 = 5^((1/3)3) to hold, so (5^(1/3)3) must equal 5.)
AII.ASE.2 Rewrite expressions involving radicals and rational exponents using the properties of exponents.
AII.ASE.3 Rewrite algebraic rational expressions in equivalent forms (e.g., using properties of exponents and factoring techniques). Add, subtract, multiply, and divide algebraic rational expressions.
- Multiply and divide rational expressions (A2-O.5)
- Add and subtract rational expressions (A2-O.6)
AII.ASE.4 Rewrite rational expressions in different forms; write a(x)/b(x) in the form q(x) + r(x)/b(x), where a(x), b(x), q(x), and r(x) are polynomials with the degree of r(x) less than the degree of b(x).
- Simplify rational expressions (A2-O.4)

AII.F Functions

AII.F.1 Understand composition of functions and combine functions by composition.
AII.F.2 Define and find the inverse of a function. Verify functions are inverses algebraically and graphically.
AII.F.3 Understand that if the graph of a function contains a point (a, b), then the graph of the inverse relation of the function contains the point (b, a); the inverse is a reflection over the line y = x.
- Find inverse functions and relations (A2-P.11)
AII.F.4 Explore and describe the effect on the graph of f(x) by replacing f(x) with f(x) + k, kf(x), f(kx), and f(x + k) for specific values of k (both positive and negative) with and without technology. Find the value of k given the graph of f(x) and the graph of f(x) + k, kf(x), f(kx), or f(x + k).

AII.SEI.2 Represent and solve real-world systems of linear equations and inequalities in two or three variables algebraically and using technology. Interpret the solution set and determine whether it is reasonable.
AII.SEI.3 Represent real-world problems using a system of linear equations in three variables. Understand that the algebraic steps to solve a two variable system can be extended to systems of equations in three variables.

AII.Q Quadratic Equations and Functions

AII.Q.1 Represent real-world problems that can be modeled with quadratic functions using tables, graphs, and equations; translate fluently among these representations. Solve such problems with and without technology. Interpret the solutions and determine whether they are reasonable.

- Complete the square (A2-K.9)
- Solve a quadratic equation by completing the square (A2-K.10)
AII.Q.3 Understand that different forms of a quadratic equation can provide different information. Use and translate quadratic functions between standard, vertex, and intercept form to graph and identify key features, including intercepts, vertex, line of symmetry, end behavior, and domain and range.
AII.Q.4 Use the discriminant to determine the number and type of solutions of a quadratic equation. Find all solutions and write complex solutions in the form of a ± bi for real numbers a and b.
- Solve a quadratic equation using the quadratic formula (A2-K.11)
- Using the discriminant (A2-K.12)
