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

Boundary
The set of points on the “edge” of a region

Complex conjugates
Complex numbers a + bi and a  bi

Gaussian elimination
A method of solving a system of n linear equations in n unknowns.

Horizontal translation
A shift of a graph to the left or right.

Intercepted arc
Arc of a circle between the initial side and terminal side of a central angle.

Length of an arrow
See Magnitude of an arrow.

Linear regression equation
Equation of a linear regression line

Logarithm
An expression of the form logb x (see Logarithmic function)

Lower bound of f
Any number b for which b < ƒ(x) for all x in the domain of ƒ

Onetoone rule of logarithms
x = y if and only if logb x = logb y.

Order of magnitude (of n)
log n.

Probability simulation
A numerical simulation of a probability experiment in which assigned numbers appear with the same probabilities as the outcomes of the experiment.

Rational zeros theorem
A procedure for finding the possible rational zeros of a polynomial.

Replication
The principle of experimental design that minimizes the effects of chance variation by repeating the experiment multiple times.

Right triangle
A triangle with a 90° angle.

Symmetric about the origin
A graph in which (x, y) is on the the graph whenever (x, y) is; or a graph in which (r, ?) or (r, ? + ?) is on the graph whenever (r, ?) is

Velocity
A vector that specifies the motion of an object in terms of its speed and direction.

Venn diagram
A visualization of the relationships among events within a sample space.
