How do you make a experiment more accurate?
To make an experiment more accurate, you can increase the sample size to reduce the effect of outliers, use control groups to isolate the variable being tested, ensure measurements are precise and consistent, and repeat the experiment multiple times to verify results.
Can a valid experiment have only one independent variable?
Yes, a valid experiment can have only one independent variable. In fact, many experiments are designed with a single independent variable to investigate its specific impact on the dependent variable while controlling for other factors. This helps researchers to isolate the effect of that variable on the outcome of the experiment.
What combination of variables will make an experiment the most reliable?
To make an experiment more reliable, it is important to have a large sample size, control for confounding variables, and ensure replicability by conducting the experiment multiple times. These factors reduce the impact of chance and increase the validity of the study findings.
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.
How could this observation be change into a valid experiment of the effects of air circulation Apex?
To conduct a valid experiment on the effects of air circulation, you could set up two identical rooms and introduce air circulation in one while leaving the other without it. Monitor various factors such as temperature, humidity, and air quality in both rooms over a period of time and compare the results. Make sure the rooms are isolated from external influences to ensure accuracy in measuring the effects of air circulation.
How do you make a test more valid?
In a valid experiment all the variables are kept the same apart from those being investigated.
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 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.
The analysis of a data gathered during a particular experiment is necessary in order to?
Draw a valid conclusion for that 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.
What is the definition of Valid Experiment?

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.
What questions should Emma ask the student to find out if the student's conclusion was valid?
I.What types of plants were used in the experiment?II.What was the experiment's control? III.Was the experiment repeated more than once?
Why do you think its important to repeat an experiment?
to make the experiment more reliable
How do you make an accurate experiment?
To make an experiment more accurate you would have to repeat the experiment 3-5 more times to make it reliable and also you would do what Liverpool college do and compare the answers with other people in the class, community or teacher.
How can you make experiment results more reliable?
There are several ways to make an experiment more valid. For example, one should always make any experiment repeatable, and they should conduct several trials before publishing results or coming to conclusions.
What is the minimum number of trials for an experiment to be valid?
3
