Quantitative Research Qualitative Research?A type of educational
research in which the researcher decides what to study.
A type of educational research in which the researcher relies on the views of the participants.

What are the characteristics of each?Quantitative Research Qualitative Research
Ask broad, general Qs.Collecting data
consisting largely of words (text) or image (picture).
Descriptions and analysis of words for themes.
Conducts inquiry in subjective, biased manner.
Ask specific narrow Qs.Collects data from
participants.Analyzes numbers using
statistics.Conducts the inquiry in
unbiased, objective manner.

What are the differences between the
two in each step?

1. Identifying a research problem.Quantitative Research Qualitative ResearchDescription of trends or
an explanation of variables’ relationships.
An exploration in which little is known about the problem.
A detailed understanding of a central phenomenon.

2. Reviewing the literatureQuantitative Research Qualitative ResearchMajor role through
suggesting the RQ to be asked.
Justifying the R problem and the need for the direction of the study.
Minor role in suggesting SRQ to be asked.
Justify the importance of studying the research problem.

3. Specifying a purpose for the researchQuantitative Research Qualitative ResearchBe specific and narrow.Seek measurable,
observable data on variables.
Be general and broad.Seek to understand the
participants’ experiences.

4. Collecting dataQuantitative Research Qualitative ResearchCollecting data using
instruments with preset Qs and Res.
Collecting info from a large number of individuals.
Collecting data using forms with general, emerging Qs to permit the participant to generate responses.
Gathering word(text) or image(picture) data.
Collecting info from a small number of individuals or sites.

5. Analyzing and Interpreting dataQuantitative Research Qualitative ResearchData analysis tends to
consist of statistical analysis.
Describing trends, comparing group differences, relating variables.
Interpretation tends to consist of comparing results with prior predictions and past research.
Text analysis.A description of themes.Stating the larger
meaning of findings.

6. Reporting and Evaluating researchQuantitative Research Qualitative ResearchTend to use standard
fixed structure and evaluation criteria.
Take an objective and unbiased approach.
A flexible, emerging structure and evaluative criteria.
Take a subjective and biased approach.

What are the research designs associated with quantitative
and qualitative research?
![Page 12: Quantitative And Qualitative Research](https://reader036.vdocument.in/reader036/viewer/2022062405/55513927b4c905325d8b54a4/html5/thumbnails/12.jpg)
Research Designs?Research designs are the specific procedures
involved in the last three steps of the research process: data collection, data analysis and report writing.
![Page 13: Quantitative And Qualitative Research](https://reader036.vdocument.in/reader036/viewer/2022062405/55513927b4c905325d8b54a4/html5/thumbnails/13.jpg)
Experimental DesignsAn independent variable is manipulated and
one or more dependent variables are controlled to see the effect of the independent variable on the dependent variable(s).
![Page 14: Quantitative And Qualitative Research](https://reader036.vdocument.in/reader036/viewer/2022062405/55513927b4c905325d8b54a4/html5/thumbnails/14.jpg)
Correlational DesignsLooking for relationships between things, even
if we don’t have a theory to explain them“fishing expedition” research - looking for what
affects what, trying to find the components for a theory

Survey Designs This involves administration of an instrument
to collect data regarding characteristics of a group.
![Page 17: Quantitative And Qualitative Research](https://reader036.vdocument.in/reader036/viewer/2022062405/55513927b4c905325d8b54a4/html5/thumbnails/17.jpg)
Grounded Disgnstheory that is developed inductively from a corpus of
data Is case-oriented; no hypothesis is testedInterviews & other data collection can be used
“constant comparison” data set theory

Ethnographic designs“The study and systematic recording of
human cultures; also : a descriptive work produced from such research
Field work; observation, interviews, questionnaires, producing description
Often related to social constructivism: how do people make sense of their world; how do they accomplish things through their practice? Source: Wikipedia

Narrative Research DesignsIn form of stories that describe the lives of
individuals and their experiences.

Mixed Method StudiesSome studies use mixed methods to collect
and analyze data…both quantitative and qualitative. For example, a person might do a quantitative survey and follow it up with qualitative interviews or focus groups. Again, the question dictates the method.

Action Designsdisciplined inquiry into practices undertaken
by those involved in themdone to inform and change the practice
studied. To address problemsOften undertaken as a collaborative activity
among colleaguesOften undertaken in situCould focus on a single issue in a classroom,
a program, etc.

Action Designsa cycle of posing questions, gathering
data, reflection, and deciding on a course of action
