Cards

Term
Theory
Definition
inter-related statements to describe an action or phenomena
Term
Theoretical framework
Definition
modeling, what concepts are being used and outcomes
Term
hypothesis
Definition
An expectation about the nature of the phenomena being observed / an educated guess
Term
construct/concept
Definition
concepts are broad description, constructs are specific and refines "something" to be measureable. both describe aspect of phenomena
Term
assumptions
Definition
statement accepted as true
Term
paradigms
Definition
concise way of thinking and looking at how things react. "the lens"; how things are looked and interpreted
Term
testability
Definition
apply quantitative methods to determine something to be possible; The ability to subject the data collected to appropriate statistical tests, in order to substantiate or reject the hypotheses developed for the research study
Term
Objectives of Science
Definition
to understand, predict, and control
Term
Deduction
Definition
start with broad theory and then work way down
Term
Induction
Definition
start with small observations and work to theory (funnel)
Term
Research
Definition
The process of finding solutions to a problem after a thoroughly study and the analysis of the situational factors. “Organize information to make meaning”
Term
Business Research
Definition
Systematic and organized effort to investigate a specific problem encountered in the work setting, which needs a solution
Term
Research Process
Definition
introduction, literature review, research methodology, data processing, conclusion
Term
Generalizability
Definition
The applicability of the research findings in one organizational setting to other settings.
**Application of your findings to the overall population
Term
Dependent Variable
Definition
The variable of primary interest to the study
Term
Independent Variable
Definition
A variable that influences the dependent or criterion variable and accounts for (or explains) its variance
Term
Moderating Variable
Definition
A variable on which the relationship between two other variables is contingent. That is, if the moderating variables are present, the theorized relationship between the two variables will hold good, but not otherwise
Term
Mediating Variable
Definition
A variable that surfaces as a function of the independent variable, and helps in conceptualizing and explaining the influence of the independent variable on the dependent variable
Term
Scales
Definition
A tool or mechanism by which individuals, events, or objects are distinguished on the variables of interest in some meaningful way
Term
Nominal Scale
Definition
A scale that categorizes individuals or objects into mutually exclusive and collectively exhaustive groups, and offers basic, categorical information onto the variable of interest
Term
Ordinal Scale
Definition
A scale that not only categorizes the qualitative differences in the variable of interest, but also allows for the rank-ordering of these categories in a meaningful way
Term
Interval Scale
Definition
A multipoint scale that taps the differences, the order, and the equality of the magnitude of the differences in the responses
Term
Ratio Scale
Definition
A scale that has an absolute zero origin, and hence indicates not only the magnitude, but also the proportion, of the differences. **Most powerful scale out of the four!
Term
Likert Scale
Definition
An interval scale that specifically uses the five anchors of Strongly Disagree, Disagree, Neither Disagree nor Agree, Agree and Strongly Agree
Term
Dichotomous Scale
Definition
Scale used to elicit a Yes/no response, or an answer to two different aspects of a concept. Nominal scale is used to elicit the response.
Term
Validity (Logic)
Definition
Evidence that the instrument, technique, or process used to measure a concept does indeed measure the intended concept. Relative measure
Term
Reliability
Definition
: Indicates the extent to which it is without bias (error free) and hence ensures consistent measurement across time and across the various items in the instrument.
Term
Strengths of Science
Definition
Easy to analyze date; Standardizes definition of phenomena; Can control/expose biases
Term
Weaknesses of Science
Definition
Cannot reflect intangible aspects; Easy to cover up biases.
