Research Methodology
• Research methodology is a way to systematically solve the research problem.
• It may be understood as a science of studying how research is done scientifically.
• In it we study the various steps that are generally adopted by a researcher in studying his research problem along with the logic behind them
![Page 9: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/9.jpg)
Research methodology..• Research Methodology says the
howto do/conduct research
systematically & scientifically.
• Research methodology not only provides
the knowledge of various types of methods & techniques
for Sampling , data collection, data analysis & report writing etc.
but also guides
that which particular method or technique
for sampling/data collection/data analysis should be used or not
& why should /shouldn't do so.

Research Methodology
• There are different ways of “knowing” and the epistemological standpoint will determine the nature of that knowing
• One may explore their reality using statistical data as evidence while another may have first-hand accounts of how the person has been effected, which is their reality.
• Each represents a particular Paradigm of knowledge. Neither is right or wrong it is just a different view.

![Page 17: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/17.jpg)
The Right and the Left
• Quantitative research - numbers, numbers, numbers
• Qualitative research - words, words, words
![Page 18: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/18.jpg)
Quantitative vs. Qualitative: Assumptions about the World• Based upon the idea of “logical
positivism”, that is, there is a singular reality with stable, social facts that are separate from the feelings and beliefs of individuals.
• Based on the notion of “constructivism”, which assumes multiple realities that are socially constructed through individual and collective perceptions or views of the same situation.
![Page 19: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/19.jpg)
Quantitative vs. Qualitative: Research Purpose
• Seeks to establish relationships and explain causes of changes in measured variables. That is, the goal of science is to explain and predict.
• Concern is with the understanding of the social phenomenon from the participants’ perspectives. This requires, to some degree, researcher participation.
![Page 20: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/20.jpg)
Quantitative vs. Qualitative: Methods and Process• The scientific method, also
known as a priori or pre-established design.
• Use of emergent design utilizing constant comparison and revision.
![Page 21: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/21.jpg)
Quantitative vs. Qualitative: Prototypical Studies• Experimental or correlational
designs are used to reduce error, bias and the influence of extraneous variables--control of bias is through design.
• Use of ethnography, which helps readers understand the multiple perspectives of the situation by the persons studied. Subjectivity in data analysis and interpretation is acknowledged.
![Page 22: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/22.jpg)
Quantitative vs. Qualitative: Researcher Role
• Detachment from study in order to avoid bias.
• Immersion in situation and the phenomenon being studied.
![Page 23: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/23.jpg)
Quantitative vs. Qualitative: Context
• Context-free generalizations • Generalizations are contextually-bound.
![Page 24: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/24.jpg)
Quantitative vs. Qualitative: Precision
• Obtained through the use of measurement and statistics
• Provided by detailed description of phenomenon
![Page 25: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/25.jpg)
Quantitative vs. Qualitative: Verification
• Results replicated by others. • Extension of understandings by others.
![Page 26: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/26.jpg)
Quantitative vs. Qualitative: Explanation
• Traditionally, parsimonious explanations were sought, but this may be changing due to technology.
• Summary through narrative--importance is placed on reducing complex realities to simple explanations.
![Page 27: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/27.jpg)
Quantitative vs. Qualitative: Logical Reasoning
• DEDUCTIVE--What’s the classic example?
• INDUCTIVE--anyone have an example?
![Page 28: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/28.jpg)
Quantitative vs. Qualitative: Conditional Conclusions• Statements of statistical
probability.• Tentative summary
interpretations.

Types of Quantitative Studies
• Descriptive
• True experimental
• Quasi-experimental
• Correlational
• Predictive
![Page 32: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/32.jpg)
Types of Qualtitative Studies
• Qualitative research gathers information that is not in numerical form:
• diary accounts,
• open-ended questionnaires,
• unstructured interviews
• unstructured observations.
• Qualitative data is typically descriptive data and as such is harder to analyze than quantitative data.
• Qualitative research is useful for studies at the individual level, and to find out, in depth, the ways in which people think or feel (e.g. case studies).
![Page 33: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/33.jpg)
Types of Qualtitative Studies
• Qualitative paradigms offer the researcher an opportunity to develop an idiographic understanding of participants’ experiences and what it means to them, within their social reality, to be in a particular situation (Bryman, 1992).
• methods include: Content / thematic analysis (CA/ TA); Grounded Theory (GT);
• Discursive psychology / Discourse analysis (DA); • Narrative psychology (NA); • Phenomenological psychology methods such as
interpretative phenomenological analysis (IPA).

Research Using Primary Data
• Cross-sectional
• Case Control
• Cohort
• Randomized controlled trial
![Page 36: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/36.jpg)
Cross-sectional Study
• Data gathered at one point in time
• Often used for surveys
• Can not make inferences about causality
![Page 37: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/37.jpg)
Case Control Study
• Start with the outcome- identify a sample with the condition of interest
• Identify a similar control group
• Look back to determine exposure
• Calculate the risk in the cases and controls- odds ratio used
• Can not use to establish prevalence
![Page 38: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/38.jpg)
Cohort Study
• Start with an identified group
• Determine exposure in everyone at the same time
• Follow the group to determine who develops the outcome of interest
• Can be used to determine prevalence
• Association measured as relative risk (rate ratios)
![Page 39: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/39.jpg)
Randomized Controlled Trial
• Gold standard for determining associations
• Identify a group
• Randomly assign individuals to exposure
• Only reliable way to control for confounding
![Page 40: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/40.jpg)
Research Using Secondary Data
• Literature review
• Systematic review
• Metanalysis
• Analysis of existing data collected for another purpose

Literature Review
• Gather articles on a topic of interest
• Summarize the findings
![Page 42: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/42.jpg)
Systematic Review
• Gather articles using a pre-defined search strategy- may include unpublished studies
• Develop a-priori objective criteria to evaluate the quality of the studies
• Summarize the quality of the data and the results
![Page 43: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/43.jpg)
Metanalysis
• Do a systematic review
• Obtain the primary data if possible
• Summarize the data quantitatively
![Page 44: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/44.jpg)
Research Method vs Methodology Comparison
Research Methods Research Methodology
• research methods are the methods by which you conduct research into a subject or a topic
• Research methods involve conduct of experiments, tests, surveys and the like
• research methods aim at finding solutions to research problems
• research methodology explains the methods by which you may proceed with your research
• research methodology involves the learning of the various techniques that can be used in the conduct of research and in the conduct of tests, experiments, surveys and critical studies search
• research methodology aims at the employment of the correct procedures to find out solutions
![Page 45: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/45.jpg)
Research Method vs Methodology ComparisonExamples:-

Research Method vs Methodology Conclusion
We can say that Research Methodology has many dimensions and Research Methods do constitute a part of the research methodology.
The scope of research methodology is wider than that of research methods.
![Page 48: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/48.jpg)
Variables
Meaning
• Known as a property of proposition being studied
• Also known as the constructs of a proposition
• A symbol to which we assign numerals or values
• Numerical value assigned to a variable is based on its
properties
• 3 types of Variables: Dichotomous; Discrete; Continuous
![Page 49: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/49.jpg)
1. Dichotomous Variables
• These variables are so called because they have TWO values, reflecting presence or absence of a property.
• For example: pass or fail, exists or does not exist, employed - unemployed, male - female, yes - no.
• The dichotomous variables can be assigned with a numerical value of ‘0’ or ‘1’ for analysis purpose.
![Page 50: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/50.jpg)
2. Discrete Variables
• These are categorical variables.
• For example, the demographic variables race or religion are the examples of discrete variables.
• Religion: Hindu, Islam, Buddhism, and Jain can be assigned numerical values of 1, 2, 3, and 4 respectively.
• The numerical values assigned to these variables will be of absolute nature; not like 3.5, or 4.7.
![Page 51: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/51.jpg)
3. Continuous Variables
• These variables take on values with a given range or, in some cases, an infinite set.
• For example, test scores may range from 0 - 100, age may be 2.5 years, present income of a person could be £. 15000, you may disclose your property worth more than £.500,000.
![Page 52: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/52.jpg)

Types of Variables
• independent variable (IV)…• what you (or nature) manipulates in
some way
• dependent variable (DV)…• what you presume to be influenced by
the IV
![Page 60: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/60.jpg)
Examples: Sports participation
IV DV
exercise participation
health status
attitude
social support
intervention

The purpose of the study was to…
• test whether the “Fair Play for Sport” curriculum is effective in promoting moral development in youth
• examine the relationship between age and VO2max.
• test whether there are gender differences the value placed on sport participation
• determine whether students’ perceptions of the amount of positive, negative, and informational feedback provided by their teachers is predictive of their self-esteem and level of achievement
IV, DV?

Types of Relationships
• correlational vs. causal relationships
correlation does not imply causation!(it’s necessary but not sufficient)
variables perform in a synchronized manner
one variable causes the other variable
![Page 63: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/63.jpg)
Types of Relationships
• patterns of relationships…• no relationship
• positive relationship
• negative relationship
• curvilinear relationship

Hypotheses
• hypothesis…• a specific statement of prediction
• types of hypotheses• alternative vs. null
• one-tailed vs. two-tailed

Hypotheses
• alternative hypothesis (HA)…• An effect (that you predict)
• null hypothesis (HO) …• Null effect

Hypotheses
hypothesis there is a relationship between age
and exercise participation
HA there is a relationship
HO there is not a relationship
this is a two-tailed hypothesis as no
direction is predicted
![Page 68: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/68.jpg)
Hypotheses
hypothesis an incentive program will increase
exercise participation
HA participation will increase
HO participation will not increase or
will decrease
this is a one-tailed hypothesis as a
specific direction is predicted

Sample vs. Population
Population = collection of ALL possible observations
Sample = subset of a population
Random Sample
representative of a population
all observations have equal chance of being selected
![Page 70: Lecture 7 research methodology in counselling](https://reader034.vdocument.in/reader034/viewer/2022042715/5595b0d41a28abfd3d8b47d5/html5/thumbnails/70.jpg)
Why Do We Use Samples?
Cost
Time
Inaccessibility of the population
Accuracy
Destruction of the observations

Sampling Methods
• Probability vs. Nonprobability
• Probability• members in the population have a known
chance (probability) of being selected into the sample
• Nonprobability• the probability of selecting members from the
population is not known

Sampling
• Once you are clear about your procedure, you need to locate participants will undergo the research procedure
• Quantitative methodology is concerned with representativeness of the sample
• The key question here is sample size as the bigger sample size the more precise the results
• Qualitative research is less focused on sample and generalizability. Sampling tends to mean a relevant case, theory base case, a critical case, an interview et cetera

Key questions to answer in your methodology• What kind of research methods are you going to use? Are they
mostly:
• Quantitative, or qualitative, or a mixture of both?
• What do you think your methods will enable you to discover?
• What might they prevent you from discovering?
• What kinds of research methods would be best suited to the kind of research you are undertaking and the research questions you are pursuing?
• What sort of problems do you envisage in setting up these methods?
• What are their benefits?
• What will you need to do to ensure they gather useful data?

Summary
• “Methodology” implies more than simply the methods you intend to use to collect data.
• It is necessary to include a consideration of the concepts and theories which underlie the methods.
• you have to show that you understand the underlying concepts of the methodology.
• When you describe your methods it is necessary to state how you have addressed the research questions and/or hypotheses.
• The methods should be described in enough detail for the study to be replicated, or at least repeated in a similar way in another situation.
• Every stage should be explained and justified with clear reasons for the choice of your particular methods and materials.
