Investigation methodology
Definition
Variables and Sources
What are Variables?
A
variable is a property that can vary (acquire various values) and whose A variable is a property that can vary (acquire various values) and whose
Information Validation
In an investigation, it is possible to formulate Descriptive Hypotheses of a Variable. Correlational Hypotheses. Group Difference Hypothesis and Causal Hypotheses?
in the same investigation it is possible to establish all the
types of hypotheses because the research problem so requires.
Hypothesis
What are Hypotheses?
We have already stated the research problem, reviewed the literature and contextual raised this problem by building the theoretical framework (which may have more or less information, depending on how much the problem or topic has been studied).
research specific).
Primary Conclusions.
What happens when no evidence is provided in favor of the hypothesis(es) of our investigation?
the data do not always support the hypotheses (from the beginning of the chapter it is He said that formulating a hypothesis does not ensure that it will be verified).
Data Collection
What does measure mean?
measure
means "assigning numbers to objects and events according to rules" (Stevens, 1951).
How do you know if a measurement instrument is reliable and valid?
The first one is improvisation. The second factor is that sometimes instruments developed in the abroad that have not been validated in our context
What does the Collection Stage imply?
Once we select the appropriate research design and sample
according to our study problem and hypothesis, the next stage
What procedure is followed to build an instrument?
the general procedure for constructing them is similar.
Before commenting on this procedure, it is necessary to clarify that in an investigation there are two options regarding the measurement instrument.
Approach
Critical Factors
What does it depend on for an Investigation to Start as Exploratory?
Descriptive, Correlational or Explanatory?
As mentioned above, there are two factors that influence whether a
research begins as exploratory, descriptive, correlational or explanatory: the state of knowledge on the research topic revealed by the review of the literature and the focus that the researcher intends to give to the study of it.
Data Development
Quantification
What are Correlational Studies?
Correlational studies measure the two or more variables that are intended to see if they are related or not in the same subjects and then the correlation is analyzed.
Qualitative Comparison
What Types of Studies Are in Behavioral Research
Human?
The next step is to choose the type of study that
we will carry out The authors classify the types of research into three: exploratory, descriptive, and explanatory studies (for example, Selltiz, Jahoda, Deutsch, and Cook, 1965; and Baby, 1979).
Foundation
File Review
Detection of literature and other documents
Dankhe (1986) distinguishes three basic types of information sources. Conduct literature review
primary sources
secondary sources
tertiary sources
Initial Observation
Some Observations on the Theoretical Framework
It is always convenient to carry out a review of the literature and present it in a organized way (call it theoretical framework or frame of reference).
Theoretical framework
What are the Functions of the Theoretical Framework?
(that is, that one has objectives and
research questions) and when their relevance and feasibility have also been evaluated, the next step is to theoretically support the study, a stage that some authors call "developing the theoretical framework".
Data Development
Have we done an adequate review of the Literature?
Sometimes one may wonder whether or not he did a correct review of the literature. and a good selection of references to integrate them into the theoretical framework.
