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 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 makes a valid experiment?
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 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.
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.
Discuss why experimental results must be reproducible in order to be considered valid?
If the experiment is not reproducible, no one can perform the experiment independently to confirm the results.
What must an experiment have in order to be valid?
to represent the population.at random. -apex (;
The analysis of a data gathered during a particular experiment is necessary in order to?
Draw a valid conclusion for that experiment.
Which procedure must be followed for the results of an experiment to be considered valid?
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.
What is the definition of Valid Experiment?
cheese
Is a valid argument strong or weak?
Valid arguments must include facts and supporting documentation in order to strengthen the validity. If not, then the argument can be challenged.
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 are the only things that can change in a valid experiment?
In a valid experiment, only the independent variable can be deliberately changed by the researcher to observe its effect on the dependent variable. Other factors, known as constants, must remain the same to ensure that any observed changes in the dependent variable are a result of the independent variable manipulation.
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 if your friend has a plan an experiment for science fair he asks for your help his topic is the strongest cloth for backpacks what variables must his experiment include?
Different types of clothing and a backpack. A backpack must be controlled in this experiment. Hope this helps students. ( Science Teacher ) :)
