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.

What does a valid experiment must include?
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 be valid an experiment must not include?
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.
To make sure an experiment's results are valid you must complete which of these tasks conduct multiple trials pick your hypothesis add bias or communicate the results.?
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.
What should the classical experiment provide the researcher with?
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.
Why is it possible to have a reliable measure that is not valid but impossible to have a valid measure that is not reliable?
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.
The analysis of a data gathered during a particular experiment is necessary in order to?
Draw a valid conclusion for that experiment.
What is the definition of Valid Experiment?

To be a valid scientific experiment the results must be?
Repeatable
What is the minimum number of trials for an experiment to be valid?
3
Why a control needed in a valid experiment?
A control is needed in a valid experiment because without controls then more then one variable is being tested. This can mess up the results.
What does a valid experiment must include?
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.
How can someone tell if a experiment is valid?
when he or she's conclusion is right
What is an experiment in which only one factor is allowed to vary?
A valid one. An experiment cannot conclusively prove anything if more than one independent variable is altered at a time. That being said, many dependent variables could show change and the experiment would still be valid, as long as only one independent variable was altered at a time. An experiment that changes only one variable at a time is called a controlled experiment.
To be valid an experiment must not include?
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.
How do you make a test more valid?
In a valid experiment all the variables are kept the same apart from those being investigated.
What steps are involved in making a valid conclusion?
Scientists use the data from an experiment to evaluate the hypothesis and draw a valid conclusion.
