Kaoyan key terms

Kaoyan · Get comfortable with the vocabulary.

Main claim

The central proposition a passage advances, distinguished from examples, background details and ideas the writer attributes to someone else.

Inference

A conclusion supported by the supplied information, which should not add an assumption merely because it sounds plausible.

Concession

Acknowledgment of a competing or limiting point within an argument, which does not necessarily abandon the main conclusion.

Referent

The word or idea to which a pronoun or expression points in context, requiring grammatical and logical agreement.

Negation scope

The part of a proposition affected by a negative expression, which can change meaning when its position or extent changes.

Translation fidelity

Preservation of the intended meaning, logical relation and degree of a source statement rather than an unrelated word-by-word arrangement.

Function domain

The set of allowed input values for a function or expression, checked before operations involving roots, logarithms and denominators.

Derivative

A local rate-of-change quantity defined by the relevant limit, distinguished from the function value or an accumulated integral.

Definite integral

A signed accumulated quantity over a specified interval, interpreted with the integrand and relevant assumptions rather than treated as always positive area.

Stationary point

A point at which the derivative is zero where it exists, which need not be a local maximum or minimum.

Matrix rank

The dimension of the independent row or column information in a matrix, distinguished from its number of entries or determinant value.

Invertibility

The existence of a matrix inverse under the applicable square-matrix conditions, not a property inferred from one nonzero entry.

Sample space

The set of outcomes described by a probability model, with equal likelihood established rather than assumed from a list.

Conditional probability

The probability of an event given another event, using the conditioning event as the reference set when its probability is positive.

Independence

A relationship in which learning one event does not change the probability of another under the specified model and conditions.

Mutual exclusivity

A relationship in which events cannot occur together in one trial, distinct from independence for positive-probability events.

Expected value

The probability-weighted average of a random quantity under a model, which need not equal any single realized observation.

Sampling bias

Systematic distortion from how observations enter a sample, which is not automatically eliminated by making the sample larger.

Course framework

The stated intellectual or curricular system within which a question asks for an interpretation, distinguished from an unqualified universal claim.

Program route

The intended admission pathway and subject combination, which must be established from actual requirements rather than assumed uniform across Kaoyan.
