Nature of Inquiry and Research Flashcards
quantitative researhc
Objective way of processing and
analyzing phenomenon in the
surroundings through the collection of
numerical data using standardized
techniques, then applying statistical
methods to come up with a
conclusion.
characteristics of quantitative research
objective, clear, systematic, feasible, deals with numbers
strengths of quantitative research
- objective - unbiased
- empirical - verifying of observable data; ability to be observed and verified. Evidence is
needed for validation, such as, references and related literature used, and the variables in the study. - data-driven - you get numerical results
- structured
- can be replicated - basis for methodology, resource, etc
WEAKNESSES OF QUANTITATIVE RESEARCH
- Large sample
- Generally expensive
- Close-ended
CLASSIFICATION OF QUANTITATIVE RESEARCH
experimental and non-experimental
experimental research
▪Treats or deals with the object or subject of the research in a definite or exact manner and determines the extent of the effects or influence of the treatment on the object/ subject, then discovers the causes of
such effects.
- requires testing and experiment
- evaluates cause and effect rs
- true experimental, quasi-experimental, pre-experimental
true experimental research
main method of applying untested research to a subject. Under true experimental conditions, participants receive randomized assignments to different groups in the study such as control group and experimental group. This removes any potential for bias in creating study groups to provide more reliable results.
quasi-experimental research
Quasi-experimental research is a type of research design that resembles experimental research but is not true experimental research. It aims to establish a cause-and-effect relationship between an independent and dependent variable, but unlike a true experiment, it does not rely on random assignment. Instead, subjects are assigned to groups based on non-random criteria
pre-experimental research
Pre-experimental research is a type of research design that is a preliminary step to justify the presence of the researcher’s intervention. It is conducted even before the true experiment starts to determine the researchers’ intervention on a group of people. This approach helps give some sort of guarantee that the experiment can be a full-scale successful study.
non-experimental research
▪A way of finding out truths about a subject by describing the collected data about such subject and determining their relationships or connections with each other
- Incapable of establishing cause-effect relationship by ITSELF.
- trend analysis, survey, historical, observational, correlational, descriptive, comparative
survey research
▪Most used non-experimental research
▪A method of research that aims at knowing what a big
number of people think and feel about some sociological issues.
- laging naka-subgroup
historical research
Refers to the use of primary historical data to answer a question. Involves developing an understanding of the past through the examination and interpretation of
evidence.
observational research
Refers to several different types of non-experimental studies in which behavior is systematically observed and recorded. The goal of observational research is to describe a variable or set of variables (usually used in
Psychology).
correlational research
Researcher measures two variables, understands, and assesses the statistical relationship between them with no influence from any extraneous variable.
▪ The variables do not connote causal relationship.
▪ The goal is to see whether one variable may predict
other variables and their relationships.
descriptive research
Involves gathering data that describe events and then organizes, tabulates, depicts, and describes the data collection. Descriptive statistics tell what is, while nferential statistics try to determine cause and effect.
