What else can I help you with?
What is meant by a controlled experiment?
A controlled experiment is one in which a control group is closely monitored. In this way, the experiment can be much more accurate as more factors are accounted for.
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.
Why do you think its important to repeat an experiment?
to make the experiment more reliable
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.
If an experiment had more than one independent variable why would that make the results of the experiment not valid?
Having more than one independent variable in an experiment can complicate the interpretation of results, as it becomes challenging to determine which variable is responsible for any observed changes in the dependent variable. This can lead to confounding effects, where the influence of one independent variable may mask or alter the effects of another. Consequently, the validity of the experiment is compromised, making it difficult to draw clear conclusions about the relationships between the variables. To ensure valid results, it's essential to isolate and manipulate one independent variable at a time.
Which will make his experiment more valid?
To make an experiment more valid, ensure that the sample size is representative of the population, use random assignment to assign participants to groups, and control for any confounding variables that could impact the results.
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.
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.

A controlled experiment is one in which a control group is closely monitored. In this way, the experiment can be much more accurate as more factors are accounted for.
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 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.
