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

  • Compound interest

  • Constant function (on an interval)

    ƒ(x 1) = ƒ(x 2) x for any x1 and x2 (in the interval)

  • Correlation coefficient

    A measure of the strength of the linear relationship between two variables, pp. 146, 162.

  • Double inequality

  • Quadric surface

    The graph in three dimensions of a seconddegree equation in three variables.

  • Semiperimeter of a triangle
