What is an hypothesis?
A testable and falsifiable explanation for a scientific explanation.
An informal observation that has not been systematically tested.
A carefully designed test, the results of which will either support or rule out a hypothesis
The group in an experiment that experiences the experimental intervention or manipulation
The group in an experiment that experiences no experimental intervention or manipulation.
A fake treatment given to control groups to mimic the experience of the experimental group.
The effect observed when members of a control group display a measurable response to a placebo because they think they are receiving a real treatment
The variable or factor being deliberately changed in the experimental group.
The measured result of an experiment, analyzed in both the experimental and the control groups.
The number of experimental subjects or the number of times the experiment is repeated
Hypothesis that is supported by years of rigorous testing and thousands of experiments
Randomized clinical trial
A controlled medical experiment in which subjects are randomly chosen to receive either an experimental treatment or a standard treatment (placebo)
the process of using observations and experiments to draw evidence-based conclusions
a process in which independent scientific experts ensure each study has been designed and interpreted appropriately
- hypotheses can never be proved true once and for all
- if a hypothesis is shown to be false, it can be rejected and removed from the list of possible answers to the original question
- if the data support the hypothesis, it will be accepted until further testing and data show otherwise
process of science
- initial observations generate questions
- study peer-reviewed scientific literature
- make scientific hypotheses that are testable and falsifiable
- carry out controlled experiments
- analyze experimental data
- make conclusions supported by data
- if results do not support hypothesis - test alternative hypothesis
- if results support hypothesis - rigorously test hypothesis with more experiments
- publish results in peer-reviewed publications
