Describe what is meant by randomized controlled double-blind trials which is used to test drugs?
Randomized controlled double blind trials is when the drug tester and the GP/Scientist both dont know what the drug is and the randomized and controlled bit means that they also don't know what they are testing the drug for e.g certain diseases but they are under observation and they are only being given tiny dosages incase of any after effects.

Is inositol effective with OCD and depression?
For some individuals, inositol provides a placebo effect and "good" results are reported. However, there are no randomized, clinically controlled trials showing that inositol provides objective benefit for individuals dealing with OCD or depression.
Which research methods determine causality?
Experimental research methods, such as randomized controlled trials, are typically used to determine causality. These methods involve manipulating an independent variable and observing its effect on a dependent variable in a controlled environment. By randomly assigning participants to different conditions, researchers can establish a cause-and-effect relationship between variables.

Which research methods can show cause and effect?
Experimental research methods, such as randomized controlled trials, are best suited to demonstrate cause and effect relationships. By manipulating an independent variable and measuring its effect on a dependent variable while controlling for confounding variables, researchers can establish a causal relationship between variables.
Who were Dr. Richard Doll and Dr. Bradford Hill?
Dr. Richard Doll was a British epidemiologist who established a strong link between smoking and lung cancer. Dr. Bradford Hill was a British medical statistician who contributed to the development of randomized controlled trials and made significant contributions to the field of epidemiology.
What are some of the possible benefits of using magnet therapy?
Magnet therapy allegedly promotes healing and decreases pain, possibly by affecting the flow of blood. However, these claims have not been verified in formal randomized controlled trials. Strong magnets, like those found in MRI machines, have little effect on ordinary humans; those used in magnet therapy are much weaker.
What is a controlled variable in experimental psychology?

What does intervention or clinical trials mean?
Clinical trials are controlled and paid experiments using humans as subjects. The clinical trials may consists of taking medicines or administration of it to an informed individual or group of informed individuals. The results from these trials are used for the improvement of certain treatment modalities or how to control a specific illness.

What research methods allows researchers to determine causality?
Experimental research methods, such as randomized controlled trials, are often used to determine causality. By manipulating an independent variable and measuring its effect on a dependent variable while controlling for other variables, researchers can establish a cause-and-effect relationship. Additionally, longitudinal studies that track changes in variables over time can also help infer causality by establishing temporal precedence.
