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

Cosecant
The function y = csc x

Directed angle
See Polar coordinates.

Direction angle of a vector
The angle that the vector makes with the positive xaxis

Ellipsoid of revolution
A surface generated by rotating an ellipse about its major axis

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

Identity matrix
A square matrix with 1’s in the main diagonal and 0’s elsewhere, p. 534.

Infinite discontinuity at x = a

Parametric curve
The graph of parametric equations.

Product of matrices A and B
The matrix in which each entry is obtained by multiplying the entries of a row of A by the corresponding entries of a column of B and then adding

Quantitative variable
A variable (in statistics) that takes on numerical values for a characteristic being measured.
