Research Design 1 Flashcards
deals with the method of selecting items
to be observed for the given study
sampling design
relates to the conditions under which the observations are to be made
observational design
concerns with the question of how many items are to be observed and how the information and data gathered are to be analysed
statistical design
deals with the techniques by which the procedures specified in the sampling, statistical and observational designs can be carried out
operational design
advance planning of the methods to be adopted for collecting the relevant data and the techniques to be used in their analysis, keeping in view the objective of the research and the availability of staff, time and money
Research design
Interviews, Observations
Exploratory Research Design
Ethnography
Descriptive Research Design
Sampling
Explanatory Research Design
Research Design can categorize into three types
1.Exploratory
2.Descriptive
3.Explanatory
variable depends upon or is a consequence of the other variable
dependent variable
variable that is antecedent to the dependent variable
independent variable
Independent variables that are not related to the purpose of the study, but may affect the dependent variable
Extraneous variable
Whatever effect is noticed on dependent variable as a result of of extraneous variable(s) is technically described as an …….
experimental error
One important characteristic of a good research design
minimise the influence or effect of extraneous variable(s)
Control
used when design the study minimising the effects of extraneous independent variables
Control
In experimental researches used to refer to restrain experimental conditions
Control
When the dependent variable is not free from the influence of extraneous variable(s), the relationship between the dependent and independent variables
The relationship is called
Confounded relationship
must contain, at least, one independent and one dependent variable
Research hypothesis
Predictive statements which are to be objectively verified or the relationships that are assumed be tested are termed ……
Research hypothesis
When the purpose of research is to test a research hypothesis
termed as …….
hypothesis-testing research
research in which an independent variable is not manipulated is called
non-experimental hypothesis-testing research
Research in which the independent variable is manipulated is termed
experimental hypothesis-testing research
a group is exposed to usual conditions
control group
a group is exposed to some novel or special condition
experimental group
different conditions under which experimental and control groups are put are usually referred to a
Treatments
process of examining the truth of a statistical hypothesis, relating to some research problem, is known as
Experiment
pre-determined plots or the blocks, where different treatments are used, are known as
Experimental unit(s)
conditions generate data that can be described in words but not in numbers
QUALITATIVE RESEARCH
Data is generated in forms of numbers
QUANTITATIVE RESEARCH
design of inquiry from the humanities in which the researcher studies the lives of individuals and asks one or more individuals to provide stories about their lives
Narrative research
design of inquiry coming from philosophy and psychology in which the researcher describes the lived experiences of individuals about a phenomenon as described by participants
Phenomenological research
design of inquiry from sociology in which the researcher derives a general, abstract theory of a process, action, or interaction grounded in the views of participants
Grounded theory
design of inquiry coming from anthropology and sociology in which the researcher studies the shared patterns of behaviors, language, and actions of an intact cultural group in a natural setting over a prolonged period of time
Ethnography
design of inquiry found in many fields, especially evaluation, in which the researcher develops an in-depth analysis of a case, often a program, event, activity, process, or one or more individuals
Case studies
involves combining or integration of qualitative and quantitative research and data in a research study
Mixed methods
Qualitative data tends to be open-ended without predetermined responses while quantitative data usually includes closed-ended responses such as found on questionnaires or psychological instruments
Mixed methods
