Bias
A flaw in the design of a sampling process that systematically causes the sample to differ from the population with respect to the statistic being measured. Undercoverage bias results when the sample systematically excludes one or more segments of the population. Voluntary response bias results when a sample consists only of those who volunteer their responses. Response bias results when the sampling design intentionally or unintentionally influences the responses

Completing the square
A method of adding a constant to an expression in order to form a perfect square

Components of a vector
See Component form of a vector.

Compound interest
Interest that becomes part of the investment

Confounding variable
A third variable that affects either of two variables being studied, making inferences about causation unreliable

Degree of a polynomial (function)
The largest exponent on the variable in any of the terms of the polynomial (function)

Halflife
The amount of time required for half of a radioactive substance to decay.

Histogram
A graph that visually represents the information in a frequency table using rectangular areas proportional to the frequencies.

Instantaneous rate of change
See Derivative at x = a.

Inverse cotangent function
The function y = cot1 x

Multiplicative identity for matrices
See Identity matrix

Multiplicity
The multiplicity of a zero c of a polynomial ƒ(x) of degree n > 0 is the number of times the factor (x  c) (x  z 2) Á (x  z n)

Observational study
A process for gathering data from a subset of a population through current or past observations. This differs from an experiment in that no treatment is imposed.

Permutation
An arrangement of elements of a set, in which order is important.

Polar coordinates
The numbers (r, ?) that determine a point’s location in a polar coordinate system. The number r is the directed distance and ? is the directed angle

Quotient rule of logarithms
logb a R S b = logb R  logb S, R > 0, S > 0

Randomization
The principle of experimental design that makes it possible to use the laws of probability when making inferences.

Solution of an equation or inequality
A value of the variable (or values of the variables) for which the equation or inequality is true
