See Inverse cotangent function.

• Chord of a conic

A line segment with endpoints on the conic

• Closed interval

An interval that includes its endpoints

• Confounding variable

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

• Coordinate(s) of a point

The number associated with a point on a number line, or the ordered pair associated with a point in the Cartesian coordinate plane, or the ordered triple associated with a point in the Cartesian three-dimensional space

• Degree

Unit of measurement (represented by the symbol ) for angles or arcs, equal to 1/360 of a complete revolution

• Inferential statistics

Using the science of statistics to make inferences about the parameters in a population from a sample.

• Length of an arrow

See Magnitude of an arrow.

• Permutation

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

• Randomization

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