  abstract is a brief overview of a research study 
•  Applied Research is conducted to generate knowledge that influences or improves practice 
• Basic Research is a Research that tests theories 
• Conceptual Definition is a variable, such as anxiety, may be defined as a feeling of uneasiness 
• concepts is the building blocks of theories 
• constitutive definition is the basic, dictionary meaning 
• Control group in experiments, the one that does not get the treatment 
• Correlational study is a type of research design that depicts a relationship between variables, but not necessarily one of cause -effect 
• data is Information used as a basis for reasoning, discussion, or calculation. 
• Delimitations addresses how the study will be narrowed in scope. 
• Dependent variable is the concept that the researcher is most interested in understanding 
• Dependent variable is the concept that the researcher is most interested in understanding 
• experiment is a research design used to find “cause-effect” relationships the “effect of…on…” 
• Experimental Group is the one that gets the treatment 
• External validity is how generalizable the results are as it concerns other populations and locations 
• extraneous variables that may influence or contaminate the data 
• heterogeneous groups under study are very different or varied. 
• homogeneous groups that are very similar 
• Independent variable is the concept being studied that usually indicates the influence or cause; the one that the researcher is manipulating 
• hypothesis is a statement written by the researcher that states the relationship among or between variables 
• Inductive Reasoning is the basis for the qualitative research approach 
• Deductive Reasoning depends on premises and is the basis for the quantitative research approach 
• Internal validity is the extent to which a study measures what it is supposed to measure (accuracy within a study) 
• Introduction establishes the scope, context and significance of the research to be conducted. 
• Limitations identify potential weaknesses of the study. 
• Measures of central tendency

  Averages e.g. the mean) 
• mean is the arithmetic average 
• median is the middle where half the scores fall above, half below, eliminates the influence of outliers 
• Methodology is a systematic approach to the conduct of a process. It includes steps of procedure, application of techniques, systems of analysis, and the modes of inquiry employed by a discipline. 
• mode is the score that occurs the most 
• Null Hypothesis is the proposition, to be tested statistically, that the experimental intervention has "no effect," meaning that the treatment and control groups will not differ as a result of the intervention. Investigators usually hope that the data will demonstrate some effect from the intervention, thus allowing the investigator to reject the null hypothesis. 
• Operational definition is how a term is used in a study 
• Participant also called respondents, their characteristics and responses are the object of study in research 
• Principle investigator  is the person who oversees a research 
• population is the target group under investigation. The population is the entire set under consideration. Samples are drawn from populations 
• Purpose of the study specific research aims and objectives for the research. 
• random

  by chance
• Qualitative Research trying to verify or generate descriptive theory that is grounded in the data gleaned from the investigation (naturalistic). 
• Quantitative Research answer a specific research question by showing statistical evidence that the data may be addressed in a particular way (experimental). 
• Questionnaire ztructured sets of questions on specified subjects that are used to gather information.
