Definition
An approach to explanation in which we seek to exhaust the idiosyncratic causes of a particular condition or event. Imagine trying to list all the reasons why you choose to attend your particular college. Given all those reasons it's difficult to imagine your making any other choice.
unique, separate, peculiar or distinct as in the word idiosyncrasy. reasons apply to one specific case.

Definition
An approach explanation in which we seek to identify a few casual factors that generally impact a class of conditions or events. Imagine two or three key factors that determine which colleges students choose-proximity, reputation, and so forth.
seeks to explain more than one event, seeks to explain "economically", using only one or just a few explanatory factors, it settles for partial rather than full explanation |

Definition
The logical model in which general principles are developed from specific observations. Having noted that Jews and Catholics are more likely to vote Democratic than Protestants are, you might conclude that religious minorities in the United States are more affiliated with the Democratic party and then your task is to explain why. This is an example of induction!
particular -> general,
specific observations ->discovery of a pattern that represents some degree of order among all given events |

Definition
The logical model in which specific expectations of hypotheses are developed on the basis of general principles. Starting from the general principle that all deans are meanies, you might anticipate that this one won't let you change courses. This anticipation would be the result of deduction
general->specific
begins with "why" and moves to "whether"
induction moves in opposite direction |

Quantification often makes our observations more explicit, easier to aggregate, compare, and summarize data. It opens up the possibility of statistical analyses, ranging from simple averages to complex formulas and mathematical models.
Quantitative data offers advantages that numbers have over words as measures of some quality, they also include disadvantages like a potential loss in richness of meaning
material, governed by rules and laws like natural sciences, limited research, positivism, truth, knowledge is collective, scientific method. causality, What is? Why do? Why Does? |

Definition
a model or frame of reference through which to observe and understand. Paradigms play a fundamental role in science just as they do in daily life.
Thomas Kuhn (1970) draws attention to the role of paradigms in the history of the natural sciences. Major scientific paradigms have included such fundamental viewpoints as:
Copernicus's conception of the earth moving around the sun(instead of reverse)
Darwin's theory of evolution
Newtonian mechanics and Einstein's relativity
Which scientific theories "make sense" depends on which paradigm scientists are maintaining |

Definition
typically done for 3 purposes: satisfy researchers curiosity and desire for better understanding, to test the feasibility of undertaking a more extensive study, to develop the methods to be employed in any subsequent study
exploring a topic, to start to familiarize a researcher with that topic. usually occurs when a researcher examines a new interest or when the subject of study itself is relatively new
exploratory studies are also appropriate for more persistent phenomena. sometimes exploratory research is pursued through the use of focus groups, or guided small group discussions. |

A major purpose of description is to describe situations and events. The researcher observes and then describes what was observed. Because scientific observation is careful and deliberate, however scientific descriptions are typically more accurate and precise than casual ones are
The U.S. census is an excellent example of descriptive social research. The goal of the census is to describe accurately and precisely a wide variety of characteristics of the U.S. population, as well as states, and counties. |

Term
|
Definition
the general purpose of this type of research is to explain things. answer ?'s of why.
ex: reporting why some people plan to vote for candidate A and others vote for candidate B is explanatory. ex: identifying why some cities have higher crime rates than others involves explanation |
|
|
Term
|
Definition
a coincidental statistical correlation between two variables, shown to be caused by some third variable , not genuine relationships
ex: there is a negative relationship b/w the number of mules and the number of Ph.D's in towns and cities: the more mules, the fewer Ph.D's and vice versa. perhaps you can think of another variable that would explain this apparent relationship. the Answer is rural versus urban settings. There are more mules in rural areas whereas the opposite is true in cities. |

Definition
necessary for a casual relationship to take effect.
ex: there is a correlation between ice cream sales and deaths due to drowning: the more ice cream sold, the drownings and vice versa. There is however NO direct link between ice cream and drowning. the third variable at work here is season or temperature. most drowning deaths occur during summer-the peak period for ice cream sales |
|
|
Term
|
Definition
an empirical relationship between two variables such that 1) changes in one are associated with changes in the other or 2) particular attributes of one variable are associated with particular attributes of the other. Correlation in and of itself does not constitute a casual relationship between the two variables, but it is one criterion of causality |

Definition
represents a condition that Must be present for the effect to follow
ex: it is necessary for you to take college courses in order to get a degree. take away the courses and the degree never follows. however simply taking the courses is not a sufficient cause of getting a degree. you need to take the right ones and pass them. |
|
|
Term
|
Definition
represents a condition that, if it is present, guarantees the effect in question. this is not to say that a sufficient cause is the only possible cause of a particular effect.
ex: skipping an exam in this course would be a sufficient cause for failing it, though students could fail it other ways as well. thus a cause can be sufficient but not necessary |

Definition
the WHAT or WHOM being studied. in social science research, the most typical units of analysis are individual people. you may note the characteristics of individual people-gender, age, region of birth, attitudes and so forth. you can then combine these descriptions to provide a composite picture of the group the individuals represent, whether a street gang or a whole society |
|
|
Term
|
Definition
erroneously drawing conclusions about individuals solely from the observation of groups. assumption that something learned about an ecological unit says something about the individuals making up that unit
|

|
Term
|
Definition
a fault of some researchers: a strict limitation (reduction) of the kinds of concepts to be considered relevant to the phenomenon under study
ex: you might attempt to predict this years winners and losers in the national basketball association by focusing on the abilities of the individual players on each team. this is certainly not stupid or irrelevant, but the sucess or failure of teams involves more than just the individuals in them; it involves coaching, team work, strategies, finances, facilities, fan loyalty and so forth. |

Term
|
Definition
a study based on observations representing a single point in time. involves observations of a sample, or cross section, of a population or phenomenon that are made at one point in time. exploratory and descriptive studies are often cross sectional.
ex: a single U.S. census for instance is a study aimed at describing the U.S. population at a given time |
|
|
Term
|
Definition
a study design involving the collection of data at different points in time. designed to permit observations of the same phenomenon over an extended period of time. changes over time
ex: a researcher can participate in and observe the activities of a UFO cult from its inception to its demise. |

Definition
a type of longitudinal study in which a given characteristic of some population is monitored over time. an example would be the series of Gallup Polls showing the electorates preferences for political candidates over the course of a campaign, even though different samples were interviewed at each point |
|
|
Term
|
Definition
a study in which some specific sub population or cohort is studied over time, although data may be collected from different members in each set of observations. for example, a study of the occupational history of the class of 1970 in which questionnaires were sent every five years would be a cohort study |

Definition
once you have a well defined purpose and a cclear description of the kinds of outcomes you want to achieve you can proceed to conceptualization:
when devising a concept or research question, it is important to specify exact meanings for all the other concepts you plan to study. specify in advance. |
|
|
Term
|
Definition
once you've specified the concepts to be studied and chosen a research method, it is time for operationalization or deciding on your measuring techniques:
the meaning of variables in a study is determined in part by how they are measured. part of the task here is deciding how the desired data will be collected: direct observation, review of official documents, a questionnaire, or some other technique |

Term
|
Definition
a variable assumed to depend on or be caused by another (called the independent variable). if you find that income is partly a function of amount of formal education, income is being treated as a dependent variable |

one step beyond conceptualization. operationalization is the process of developing operational definitions, or specifying the exact operations involved in measuring a variable |
|
|
Term
|
Definition
the concrete and specific definiton of something in terms of the operations by which observations are to be catergorized. the operational definition of "earning an A in this course" might be "correctly answering at least 90% of the final exam questions" |
