To improve the validity of an experiment, ensure that the experiment is well-designed with controlled variables to isolate the effect of the independent variable on the dependent variable. Use random sampling to select participants and random assignment to groups to minimize bias. Additionally, replicate the experiment to confirm results and gather more data for robust conclusions. Finally, ensure that measurement tools and methods are reliable and valid for assessing the outcomes.
What else can I help you with?
When the experiment is complete what does the researcher do?
Repeats the experiment for validity
What is the soundness of conclusions can be drawn from an experiment?
Validity
What is the soundness of the conclusions that can be drawn from an experiment?
Validity
Are control variables those that are changed in an experiment?
No, control variables are not the ones changed in an experiment; rather, they are the factors that are kept constant to ensure that any observed effects can be attributed to the independent variable. By controlling these variables, researchers can minimize their influence and isolate the relationship between the independent and dependent variables. This helps improve the reliability and validity of the experiment's results.
What are the factors in an experiment that are kept the same every time you do the experiment?
The factors in an experiment that are kept the same every time are called controlled variables. These can include elements like temperature, time, equipment, and materials used. By keeping these variables constant, researchers can ensure that any changes in the outcome of the experiment are due to the independent variable being tested, rather than other influences. This helps to improve the reliability and validity of the results.

What increases the validity of an experiment?
Repeated trials of said experiment.
Can a study have internal validity but not external validity?
Yes. Internal validity is whether or not the experiment is studying what it intends to. External validity is whether or not the study can be generalised outside of the study. For example, if you had a perfect experiment set up, that measures something perfectly, then it will have internal validity. You haven't, however, shown that you would get the same results in different cultures, or in different time periods. Thus the experiment may not have external validity.

Validity
What is the questionable outcome of the experiment?
The questionable outcome of the experiment is the validity or reliability of the results obtained.
How does sample size affect the validity of an experiment?
The sample size has no effect on the validity of an experiment: instead, it is the experimental procedure and integrity of the experimenters.The sample size can affect conclusions that may be drawn from an experiment. The larger the sample is, the more reliable these conclusions are.
What is an open experiment?
an experiment where the subjects know what is going on. they are not tricked or fooled with any tactics to increase validity such as placebos etc.
Is a testable hypotheses?
One where the validity of the hypothesis can be determined by some test or experiment.
Are control variables those that are changed in an experiment?
No, control variables are not the ones changed in an experiment; rather, they are the factors that are kept constant to ensure that any observed effects can be attributed to the independent variable. By controlling these variables, researchers can minimize their influence and isolate the relationship between the independent and dependent variables. This helps improve the reliability and validity of the experiment's results.
Why do scientists perform three trials for their experiment?
Scientists perform three trials for their experiment to increase the reliability of their results. By conducting multiple trials, scientists can assess the consistency and reproducibility of their findings, reducing the impact of outliers or random variability. This approach helps to improve the confidence in the validity of the experimental results.
