The contribution of quantitative and qualitative research methods Flashcards
What is meant by quantitative research methods?
research methods based on quantifiable (numbers) data. They are associated with the natural-science approach based on the hypothetico-deductive model.
Name and describe six assumptions of quantitative research
• Realism: phenomena in the world have an existence outside people’s mind (realism), which can be
discovered by using the scientific method.
• Causality: the main aim of research is to find universal causal relationships.
• Confounds and noise: the presence of confounding and random variables (noise) are to be avoided.
• Bias: standardized measurements and instruments are used to avoid researcher biases.
• Falsification: researchers continuously evaluate the truth of their conclusions.
• Nomothetic approach: studies are in search of universal principles that exceed the confines of the study.
The various quantitative research techniques are divided into what 3 broad orientations?
(1) descriptive research,
(2) relational research and
(3) experimental research.
What is involved in descriptive research?
The focus in this orientation is on observation. Data are gathered in a numerical form, by collecting measurements or counting frequencies of occurrence.
Give two reasons why the majority of descriptive studies involve the collection of a few data points per participants from a large group of participants
- The larger the sample, the more representative it becomes.
* Large numbers of observation yield more precise statistics.
What does relational research involve?
To find out whether 2 variables are related measures of both are collected and correlated.
Why is calculating and using statistical correlation co-efficients important?
Calculating and using statistical correlation coefficients is important, because people are prone to illusory correlations. (perception of a correlation between events for which no independent evidence can
be found. )
Name a statistical technique often used in relational research
Factor analysis = a statistical technique calculating how many factors are needed to account for the
correlations between the variables measured and how they relate to the factors.
When is experimental research needed? What is important to do to insure that you are measuring what you are supposed to be measuring?
Because correlations do not allow certainty about cause and effect relationships, therefore, experimental research is needed. . It is important to control for confounding variables to be sure that resulting changes are due to the independent variable.
Name four weaknesses to quantitative research
No interest in individuals-Quantitative research is designed in such a way that each participant returns 1 or a few numbers, to be used in statistical analysis. There is a lack of interest in the person behind the participants, which is particularly concerning when it concerns real-life situations.
Quantitative imperative = a bias only to find measurable topics interesting because quantitative research methods require numerical data. Because of this, aspects of mental life that can’t be captured by numbers have been considered less important.
Emphasis on falsification= The emphasis on falsification is primarily geared towards erasing wrong theories rather than generating new ones. As a result, it is not unusual to see theories that have been discredited for some time still being rejected, just because it is easy to disprove them. Thus, progress can be very slow.
Better suited to testing general theories than finding solutions to specific problems
Describe the six assumptions underly qualitative research
• Idealism: there is little to no evidence for a reality outside people’s minds. The only reality that matters is
the reality as perceived and constructed by people.
• Control: attempting to control the situation makes the setting artificial and thus, doesn’t help to make the
‘real world’ visible.
• Immersion: the researcher is immersed in the situation that is being studied, so that the meaning can be
understood. The researcher approaches the situation open-mindedly and sees what comes out.
• Ideographic approach: the conclusions of the study stay limited to the phenomenon under study.
• Induction: instead of reliance on the hypothetico-deductive model, more attentions is on inductive
reasoning and bracketing.
• Evidence-based: even though the data are typically not numbered, conclusions still need to be able to be
verified by others. Research is not intuition and opinion based.
What is meant by bracketing?
Requirement in qualitative research to look at a phenomenon with an open mind and to free oneself from preconceptions (such as hypotheses).
What is the most frequently used technique of data collection in qualitative research?
The semi-structured interview. It allows a limited set of core question while still allowing the participant to lead the way.
Name and describe a group format of the semi-structured interview
Focus group = technique in which a group of participants freely discusses a limited set of questions.
What is meant by a transcription?
Transcription- The raw data of interviews consist of auditory or visual recording. These are transcribed in written form, so that they can easily be referred to.
