- confessional television — television programmes, esp talk shows, in which members of the public reveal their private lives, personal problems, etc
- conformational analysis — the study of the spatial arrangement of atoms or groups of atoms in a molecule and the way in which this influences chemical behaviour
- conjunctive normal form — (logic) (CNF) A logical formula consisting of a conjunction of disjunctions of terms where no disjunction contains a conjunction. Such a formula might also be described as a product of sums. E.g. the CNF of (A and B) or C is (A or C) and (B or C). Contrast Disjunctive Normal Form.
- constant of gravitation — a law stating that any two masses attract each other with a force equal to a constant (constant of gravitation) multiplied by the product of the two masses and divided by the square of the distance between them.
- constant of integration — a constant that is added to the function obtained by evaluating the indefinite integral of a given function, indicating that all indefinite integrals of the given function differ by, at most, a constant.
- constraint satisfaction — (application) The process of assigning values to variables while meeting certain requirements or "constraints". For example, in graph colouring, a node is a variable, the colour assigned to it is its value and a link between two nodes represents the constraint that those two nodes must not be assigned the same colour. In scheduling, constraints apply to such variables as the starting and ending times for tasks. The Simplex method is one well known technique for solving numerical constraints. The search difficulty of constraint satisfaction problems can be determined on average from knowledge of easily computed structural properties of the problems. In fact, hard instances of NP-complete problems are concentrated near an abrupt transition between under- and over-constrained problems. This transition is analogous to phase transitions in physical systems and offers a way to estimate the likely difficulty of a constraint problem before attempting to solve it with search.
- correct me if i'm wrong — You say 'correct me if I'm wrong' to indicate that you are not entirely sure that what you are about to say is true.
- correlation coefficient — a statistic measuring the degree of correlation between two variables as by dividing their covariance by the square root of the product of their variances. The closer the correlation coefficient is to 1 or –1 the greater the correlation; if it is random, the coefficient is zero

- disjunctive normal form — (DNF) A logical formula consisting of a disjunction of conjunctions where no conjunction contains a disjunction. E.g. the DNF of (A or B) and C is (A and C) or (B and C).
