|
|
Term
|
Definition
Data collected by polling and research studies that can be used to make statistical generalizations. |
|
|
Term

|
|
Term

A quality of a research sample in which the sample has the same significant characteristics in the same proportion as the target population. |
|
|
Term
|
Definition

|
|
Term

Definition
A condition that allows every member of a target population to have an equal chance of being chosen as part of the sample. |
|
|
Term
|
Definition
Generalizations based on causal factors; that is, they state that a particular factor is responsible for a specific effect. These generalizations are used to strengthen inductive arguments. |
|
|
Term
|
Definition
A condition (state of affairs, thing, process) that must be present if a particular effect is present. Equivalently, if the necessary condition is absent, then the effect cannot occur. |
|
|
Term
|
Definition
A condition (state of affairs, thing, process) that automatically leads to the production of another event. If the condition is present, then the effect will definitely occur. The sufficient condition creates or causes the effect. |
|

Term
|
Definition
A combination of causes that are presumed to lead to a specific effect. |
|
|
Term
|
Definition
A causal factor that immediately precedes the effect. |
|
|
Term
|
Definition
Factors or conditions that led up to but did not immediately precede the effect. |
|
|
Term
|
Definition
A theory of causation postulating that the cause of an effect is found by noting that X is the only factor always present when Y (the problem or the good effect) occurs; therefore, X causes Y . |
|
|
Term
|
Definition
A theory of causation postulating that the cause of an effect is found by noting that the only difference between the event or effect (called Y) happening or not happening is whether one element—X—is present. |
