more than one variable
To be valid, an experiment must not include bias, confounding variables, or unreliable measures in order to accurately assess the cause-and-effect relationship between variables.
A valid experiment must include a control group for comparison, random assignment of participants to groups, manipulation of an independent variable, and measurement of a dependent variable to test the hypothesis.
To ensure an experiment's results are valid, you must conduct multiple trials to account for variability and increase reliability. This helps to minimize potential errors and ensure that the results are consistent and reproducible.
A valid experiment is characterized by a clear hypothesis, a control group for comparison, random assignment of participants, and the ability to replicate the results. It should also have ethical considerations and controls in place to minimize bias and confounding variables.
A classical experiment should provide the researcher with reliable and valid data to test a hypothesis. It should allow the researcher to establish cause-and-effect relationships and draw meaningful conclusions based on the results.
A reliable measure is consistent and yields consistent results, so it may not be measuring the intended construct accurately (lack validity). On the other hand, a valid measure accurately assesses the intended construct, but it must be consistent and produce stable results (reliable) to ensure that the measurements are dependable and trustworthy.
A valid experiment must include a control group for comparison, random assignment of participants to groups, manipulation of an independent variable, and measurement of a dependent variable to test the hypothesis.
Repeatable
If the experiment is not reproducible, no one can perform the experiment independently to confirm the results.

Draw a valid conclusion for that experiment.
Valid elements of a contract include both parties signatures. A contract must also include both parties agreeing on the terms of the contract.
A valid experiment is the one which is done on the basis of some facts and figures. The experiment which has a good statistical analysis is known to be valid experiment.step 3.

Valid arguments must include facts and supporting documentation in order to strengthen the validity. If not, then the argument can be challenged.
To ensure an experiment's results are valid, you must conduct multiple trials to account for variability and increase reliability. This helps to minimize potential errors and ensure that the results are consistent and reproducible.

Different types of clothing and a backpack. A backpack must be controlled in this experiment. Hope this helps students. ( Science Teacher ) :)
