20 cards. Read the term and the definition here. The deck at the top of this page is optional.
- Premise
- A statement accepted as given for an argument; its role in an exercise does not establish its factual truth outside that exercise.
- Conclusion
- The claim an argument attempts to support using its premises; distinguish this claim from background information and a restatement of the evidence.
- Sufficient condition
- A condition whose truth guarantees another statement under a specified implication, without requiring that it be the only way to obtain that result.
- Necessary condition
- A requirement that must hold if a target statement holds, although meeting the requirement alone need not guarantee the target statement.
- Contrapositive
- The implication formed by reversing and negating a conditional: if P implies Q, then not Q implies not P in classical logic.
- Counterexample
- A situation consistent with the stated premises in which a proposed universal conclusion fails, demonstrating that the conclusion is not logically necessary.
- Confounding
- A situation in which another factor influences the compared variables and can help explain an observed association without the proposed direct causal relationship.
- Denominator
- The reference quantity in a ratio; changing this reference can change a percentage even when the numerator remains the same.
- Weighted mean
- A combined average found by multiplying each value by its relevant weight, adding the products and dividing by the sum of weights.
- Percentage point
- A unit for the arithmetic difference between percentage values, distinct from relative percentage growth measured against an initial value.
- Rate
- A quantity expressed per unit of another quantity, such as completed cases per hour; identify the units before combining or converting rates.
- Sample space
- The set of possible outcomes under a specified probability model; probabilities depend on which outcomes and selection assumptions the model includes.
- Expected value
- The probability-weighted mean of possible numerical outcomes, representing a model average rather than a guaranteed result in one individual trial.
- Selection bias
- Systematic differences introduced by how observations enter a sample, limiting how reliably their observed pattern represents the intended target population.
- Constraint
- An explicit restriction on permissible arrangements or decisions; a proposed solution is valid only if it satisfies every relevant restriction simultaneously.
- Feasible arrangement
- A complete assignment that meets all stated restrictions; one example proves possibility but does not show that every solution has the same property.
- Immediate precedence
- An ordering requirement placing one item directly before another with no intervening item, stronger than an unspecified earlier position.
- Authorization
- Permission for a particular action within a stated role and set of conditions; permission for one action does not automatically permit related actions.
- Escalation
- Referral of an unresolved issue through the appropriate authorized decision route, accompanied by accurate evidence and the limits of the authority of the referring person.
- Audit trail
- A record of actions and changes that allows later review of what happened, when it happened and the evidence supporting a decision.
