An generalization that presents a representation about relationships among phenomena
Variable
A quality of interest or concepts that can be manipulated, observed or studied
Independent variable
The concept being studied that usually indicates the influence or cause; the one that the researcher is manipulating
Dependent variable
The concept that the researcher is most interested in understanding
Extraneous variables
Variables that may influence or contaminate the data
Heterogeneous
Groups under study are very different or varied
Homogeneous
Groups that are very similar
Conceptual definition
A variable, such as anxiety, may be defined as a feeling of uneasiness
Operational definition
How a term is used in a study
Hypothesis
A statement written by the researcher that states the relationship among or between variables
Quantitative research
Answer a specific research question by showing statistical evidence that the data may be addressed in a particular way (experimental)
Qualitative research
Trying to verify or generate descriptive theory that is grounded in the data gleaned from the investigation (naturalistic)
Deductive reasoning
Depends on premises and is the basis for the quantitative research approach
Inductive reasoning
The basis for the qualitative research approach
Relationship
The bond or connection between two variables
Applied research
Conducted to generate knowledge that influences or improves practice
Basic research
Research that tests theories
Abstract
A brief overview of a research study
Questionnaire
Structured sets of questions on specified subjects that are used to gather information
Random sample
Everybody has the same chance of being assigned to any group
Standard deviation
A measure of spread; the average deviation of a group of scores from the mean
Statistics
Mathematical tools based on the normal curve used to analyze data; it must match with research designs
Statistical significance
An important finding that did not likely happen by chance
Research design
The method for finding out what the researcher wants to know, experiment, and correlate
Research methodology
The method of research design (paradigm as well as statistics and analysis) as well as the approximate timeline for completion of the study
Sample
A smaller group that represents population of interest
Population
The target group under investigation. The population is the entire set under consideration
Participant
Also called respondents, their characteristics and responses are the object of study in research
Significance of the study
It is written as part of the introduction section of a thesis. It provides details to the reader on how the study will contribute such as what the study will contribute and who will benefit from it
Statement of the problem
Part of the introduction which enumerates the research questions which the study sought to answer
Delimitations
It addresses how the study will be narrowed in scope
Limitations
Identify potential weaknesses of the study
Introduction
Establishes the scope, context and significance of the research to be conducted
Experiment
A research design used to find "cause-effect" relationships the "effect of…on…"
Descriptive study
Research design that describes "what is" e.g. a survey
Correlational study
A type of research design that depicts a relationship between variables, but not necessarily one of cause -effect
