Experimental research is a kind of study that rigidly follows a scientific research design. It
involves testing or attempting to prove a hypothesis by way of experimentation
. As such, it uses one or more independent variables, manipulating them and then using them on one or more dependent variables.
What is an example of experimental research?
For example, in order
to test the effects of a new drug intended to treat a certain medical condition
like dementia, if a sample of dementia patients is randomly divided into three groups, with the first group receiving a high dosage of the drug, the second group receiving a low dosage, and the third group receives a …
What is the meaning of experimental research?
Experimental research is
a study that strictly adheres to a scientific research design
. It includes a hypothesis, a variable that can be manipulated by the researcher, and variables that can be measured, calculated and compared. Most importantly, experimental research is completed in a controlled environment.
Why experimental research is important?
Experiments are
conducted to be able to predict phenomenons
. Typically, an experiment is constructed to be able to explain some kind of causation. Experimental research is important to society – it helps us to improve our everyday lives.
What are the 4 types of experimental research?
- Pre-experimental research design.
- True experimental research design.
- Quasi-experimental research design.
What are the main conditions of experimental research?
Experimental research involves the differentiation of two basic conditions:
exposure and non-exposure to the treatment condition of the independent variable
. The experimental group is the group exposed to the treatment condition, while the control group is not subjected to treatment.
Which is better the two types of experimental research?
True experiments
, in which all the important factors that might affect the phenomena of interest are completely controlled, are the preferred design. Often, however, it is not possible or practical to control all the key factors, so it becomes necessary to implement a quasi-experimental research design.
What are the 3 characteristics of experimental research?
Several kinds of experimental designs exist. In general, designs that are true experiments contain three key features:
independent and dependent variables, pretesting and posttesting, and experimental and control groups
. In a true experiment, the effect of an intervention is tested by comparing two groups.
What is an example of experimental psychology?
For example,
researchers could perform a study to look at whether sleep deprivation impairs performance on a driving test
. The experimenter could control for other variables that might influence the outcome, but then vary the amount of sleep that participants get the night before a driving test.
Which one is an example of pre-experimental research?
One type of pre-experimental design is the one shot case study in which one group is exposed to a treatment or condition and measured afterwards to see if there were any effects. There is no control group for comparison. An example of this would be
a teacher using a new instructional method for their class
.
What are the steps of experimental research?
- State the hypothesis to be tested. …
- Formulate a context. …
- Formulate a theoretical model. …
- Design the experiment. …
- Construct the experiment.
- Test the experimental apparatus. …
- Perform preliminary experiments. …
- Perform the experiment.
What is the importance of non experimental research?
Some advantages of non-experimental research are:
It is very flexible during the research process
.
The cause of the phenomenon is known
, and the effect it has is investigated. The researcher can define the characteristics of the study group.
Is main part of experimental research?
The main elements of experimental research are
control, manipulation, random selection, and random assignment
.
What are the different types of experimental research?
Pre-experimental, quasi-experimental, and true experimental designs
are the three basic kinds of experimental research designs. A special type of experimental design is determined by the degree to which the researcher assigns subjects to the different conditions and groups [4].
What are the major classification of experimental research?
The types of experimental research design are determined by the way the researcher assigns subjects to different conditions and groups. They are of 3 types, namely;
pre-experimental, quasi-experimental, and true experimental research.
What are the different types of experimental methods?
- Lab Experiment. Lab Experiment. A laboratory experiment is an experiment conducted under highly controlled conditions (not necessarily a laboratory), where accurate measurements are possible. …
- Field Experiment. Field Experiment. …
- Natural Experiment. Natural Experiment.
