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 else can I help you with?
Why is using two manipulated variables in an experiment would not work?
Using two manipulated variables in an experiment can make it difficult to determine which variable is actually causing a change in the outcome. This can lead to confounding variables and make it challenging to draw clear conclusions about the relationship between the variables and the outcome. It's important to isolate and study one variable at a time to accurately understand its impact.
Instruments and our senses Are used to make what during an experiment?
Instruments and our senses are used to collect and analyze data during an experiment. This data is essential for drawing conclusions and making observations about the experiment's variables and outcomes.
When an experiment shows that one variable make another variable change and no other varibles have any effect the experiment shows?
The experiment shows a direct causal relationship between the two variables, indicating that changes in one variable lead to changes in the other. This demonstrates the impact of the manipulated variable on the outcome, without interference from other variables.
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 many variables do you change at one time during an experiment?
To ensure valid results, it is best to only change one variable at a time during an experiment. This allows you to understand the specific impact of that variable on the outcome. Changing multiple variables simultaneously can make it difficult to determine which factor is responsible for any observed changes.
What are control variables important in experimenting?
the reason it is important to controll the variables in an experiment is because if the variables are not controlled in an experiment it will be impossible to reproduce the experiment. which also will make it impossible to prove the theory being tested
Why do you think its important to repeat an experiment?
to make the experiment more reliable
What would make the results of this experiment reliable?
performing the experiment multiple times
The difference between the independent and dependent variables?
Independent variables are variables that can be changed in an experiment, while dependent variables are variables that change as a result of an experiment. In other words, independent variables are what you change, and dependent variables are the results of the experiment.
When you make a conclusion about an experiment what do you need to concider?
You need to consider the results, your hypothesis, and the variables and controls used throughout the experiment.
Why do you perform numerous trials of an experiment?
to make your results more reliable
When you make a conclusions about an experiment what do you need to consider?
the variables and the facts so you don't make any mistakes about the conclusion.
What would make experimental results more reliable?
performing the experiment multiply times.

Why is it so important to control variables in an experiment?
You need to control variables in an experiment so as to make sure that only the variable you are testing and changing is the one affecting the results of your experiment. For example, in an experiment to find the effect of light intensity on the rate of photosynthesis of plant, you'll change light by putting a plant in sun and another in dark but you must not change carbon dioxide level for both plants so by that you have controlled other variables in the experiment(variables which must be the same always in the experiment).
What does the word dependent variable mean in science?
In an experiment the variables whose values are measured. A scientist measures how these variables respond to changes they make in an independent variable.
Why do scientists try to control most variables in an experiment or observational study?
To make "the most correctable solution"
