One of the main strengths of
experimental research
is that it can often determine a cause and effect relationship between two variables. By systematically manipulating and isolating the independent variable, the researcher can determine with confidence the independent variable’s causal effect on the dependent variable.
What type of study can determine cause and effect relationships?
A controlled experiment
is the only research method that can establish a cause and effect relationship.
What is the only research method that isolates cause and effect?
A controlled experiment
is the only research method that can establish a cause and effect relationship.
What is the best research method for investigating cause and effect relationships between variables?
1.
Causal or Experimental Research
. When most people think of scientific experimentation, research on cause and effect is most often brought to mind. Experiments on causal relationships investigate the effect of one or more variables on one or more outcome variables.
Which type of research provides the strongest evidence about cause and effect relationships?
In an experiment, researchers use a variety of techniques to eliminate the influence of these other factors. Then they manipulate the explanatory variable to see if it affects the response. For this reason,
experiments
give the strongest evidence for a cause-and-effect relationship.
How do you determine a cause and effect relationship?
To find cause and effect relationships, we look for
one event that caused another event
. The cause is why the event happens. The effect is what happened. Sometimes there can be more than one cause and effect.
What are the examples of cause and effect relationship?
Cause and effect is the
relationship between two things when one thing makes something else happen
. For example, if we eat too much food and do not exercise, we gain weight. Eating food without exercising is the “cause;” weight gain is the “effect.” There may be multiple causes and multiple effects.
Which type of research is best for establishing cause and effect?
A controlled experiment
is the only research method that can establish a cause and effect relationship.
What are the characteristics of experimentation that make it possible to isolate cause and effect?
Answer Expert Verified. Experimentation makes it possible for researchers to isolate cause and effect by
allowing the researchers to manipulate one factor while controlling the other factors
. This is achieved by creating two groups, subjects are put in these groups randomly in order to reduce experimental biases.
How does a control group increase validity?
Control groups help ensure
the internal validity of your research
. You might see a difference over time in your dependent variable in your treatment group. However, without a control group, it is difficult to know whether the change has arisen from the treatment.
What are two research methods for exploring the cause and effect relationships between variables?
There are two research methods for exploring the cause and effect relationship between variables:
Experimentation, and
.
Simulation
.
What is the only way to determine a causal relationship between two variables?
Fundamentally, the only way to establish a causal relationship is
to rule out other plausible explanations for the correlation
.
Are correlations important as cause and effect relationships?
This means that the experiment can predict cause and effect (causation) but
a correlation can only predict a relationship
, as another extraneous variable may be involved that it not known about.
Which type of research is likely to provides the strongest evidence?
Systematic Reviews and Meta Analyses
Well done systematic reviews
, with or without an included meta-analysis, are generally considered to provide the best evidence for all question types as they are based on the findings of multiple studies that were identified in comprehensive, systematic literature searches.
What type of research is most controlled?
- Experiments are generally the most precise studies and have the most conclusive power. …
- A well-designed experiment has features that control random variables to make sure that the effect measured is caused by the independent variable being manipulated.
Which experimental study has the strongest evidence?
An RCT
is the highest level of primary evidence and is a “true experiment” in which eligible individuals are randomly assigned to either the experimental or control group.
