Conjunctive tasks are tasks requiring all group members to contribute to complete the product. [1] In this type of task the group's performance is determined by the most inferior or weakest group member. [2] Examples provided in Forysth's summary of Steiner's work include climbing a mountain and eating a meal as a group. [2]
Disjunctive Rule: Similar to the conjunctive rule, consumers may determine a cut-off point for each salient attribute of the products in the consideration set. Then, conversely, the first brand which meets the cut-off point for only one attribute is selected.
A set of rules can be used to infer any valid conclusion if it is complete, while never inferring an invalid conclusion, if it is sound. A sound and complete set of rules need not include every rule in the following list, as many of the rules are redundant, and can be proven with the other rules.
In decision theory, a decision rule is a function which maps an observation to an appropriate action. Decision rules play an important role in the theory of statistics and economics , and are closely related to the concept of a strategy in game theory .
In propositional logic, disjunction elimination [1] [2] (sometimes named proof by cases, case analysis, or or elimination) is the valid argument form and rule of inference that allows one to eliminate a disjunctive statement from a logical proof.
In logic, a clause is a propositional formula formed from a finite collection of literals (atoms or their negations) and logical connectives.A clause is true either whenever at least one of the literals that form it is true (a disjunctive clause, the most common use of the term), or when all of the literals that form it are true (a conjunctive clause, a less common use of the term).
In some experimental demonstrations, the conjoint option is evaluated separately from its basic option. In other words, one group of participants is asked to rank-order the likelihood that Linda is a bank teller, a high school teacher, and several other options, and another group is asked to rank-order whether Linda is a bank teller and active in the feminist movement versus the same set of ...
Chrysippus seems to have been responsible for introducing the three main types of connectives: the conditional (if), conjunctive (and), and disjunctive (or). [26] A typical conditional takes the form of "if p then q"; [27] whereas a conjunction takes the form of "both p and q"; [27] and a disjunction takes the form of "either p or q". [28]
