What is the term used to describe the experimental treatment initiated by the researcher quizlet?
What is the term used to describe the experimental treatment initiated by the researcher? Independent variable. By what specific criterion should you judge the results or findings of experimental research?
How would you describe an experimental study design?
Experimental design is the process of carrying out research in an objective and controlled fashion so that precision is maximized and specific conclusions can be drawn regarding a hypothesis statement. Generally, the purpose is to establish the effect that a factor or independent variable has on a dependent variable.
What is treatment in experimental research?
The treatment is any independent variable manipulated by the experimenters, and its exact form depends on the type of research being performed. In a medical trial, it might be a new drug or therapy. In public policy studies, it could be a new social policy that some receive and not others.
What is the term used to describe the outcome measured by the researcher?
The outcome measure is also called the dependent variable. Another term for the outcome measure is the ___________ variable. independent variable. The experimenter manipulates the independent variable.
When should a descriptive or exploratory design be used?
A descriptive or exploratory design is appropriate when little is known about a research topic. Cause and effect are determined by both quasiexperimental and experimental designs. 3.
How do researchers conduct experimental research?
Experimental research is usually conducted in a controlled laboratory environment. The researcher collects data that will either support or reject the hypothesis through data analysis. Experimental research is also sometimes called hypothesis testing or a method of deductive research.

What is experimental study in research?
Experimental studies are ones where researchers introduce an intervention and study the effects. Experimental studies are usually randomized, meaning the subjects are grouped by chance.
What is the purpose of treatment in research?
Treatment groups are the sets of participants in a research study that are exposed to some manipulation or intentional change in the independent variable of interest. They are an integral part of experimental research design that helps to measure effects as well as establish causality.
What is treatment of the data in research?
What is Statistical Treatment of Data? Statistical treatment of data is when you apply some form of statistical method to a data set to transform it from a group of meaningless numbers into meaningful output.
Why do we do clinical trials?
Clinical trials are conducted for many reasons: 1 to determine whether a new drug or device is safe and effective for people to use. 2 to study different ways to use standard treatments or current, approved treatments so that they will be more effective, easier to use, or decrease certain side effects. 3 to learn how to safely use a treatment in a population for which the treatment was not previously tested, such as children.
Why do people participate in clinical trials?
Some people participate in clinical trials because none of the standard (approved) treatment options have worked, or they are unable to tolerate certain side effects. Clinical trials provide another option when standard therapy has failed.
How does the FDA work?
FDA works to protect participants in clinical trials and to ensure that people have reliable information before deciding whether to join a clinical trial. The Federal government has regulations and guidelines for clinical research to protect participants from unreasonable risks.
What is a protocol in clinical research?
Clinical trials are conducted according to a plan, called a protocol, which describes: what the researchers hope to learn from the study. Volunteers who participate in the study must agree to the rules and terms outlined in the protocol. Similarly, researchers, doctors, and other health professionals who manage the clinical trials must follow ...
What does the FDA do?
FDA seeks to ensure that people of different ages, races, ethnic groups, and genders are included in clinical trials. Learn more about FDA’s efforts to increase diversity in clinical trials.
What are the criteria for clinical trials?
All clinical trials have guidelines, called eligibility criteria, about who can participate. The criteria are based on such factors as age, sex, type and stage of disease, previous treatment history, and other medical conditions.
Why is it important to test drugs and medical products in the people they are meant to help?
It is also important to conduct research in a variety of people, because different people may respond differently to treatments. FDA seeks to ensure that people of different ages, races, ethnic groups, and genders are included in clinical trials.

What is experimental design?
Experimental design means planning a set of procedures to investigate a relationship between variables. To design a controlled experiment, you need: A testable hypothesis. At least one independent variable that can be precisely manipulated. At least one dependent variable that can be precisely measured.
What is a control group in a test?
You should also include a control group, which receives no treatment. The control group tells us what would have happened to your test subjects without any experimental intervention.
