Changing only one variable at a time in an experiment allows us to clearly identify the effect of that specific variable on the outcome. By isolating variables, we can determine causality and understand the relationship between the variable being tested and the results observed. This approach helps in drawing reliable conclusions and making accurate predictions.
When more than one variable is changed at a time in an experiment, it becomes difficult to determine which variable is responsible for any observed effects. This can lead to confounding variables and make it challenging to draw meaningful conclusions from the data. It is best practice in experimental design to change only one variable at a time to accurately assess its impact.
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.
By changing only one variable at a time, the investigator can determine the specific effect that variable has on the outcome of the experiment. This allows for a clear cause-and-effect relationship to be established. Changing multiple variables simultaneously would make it difficult to determine which variable is responsible for any observed changes.
The term for an experiment in which only one variable is changed at a time is called a controlled experiment. This allows researchers to isolate the effect of that specific variable on the outcome of the experiment.
A variable that doesn't change in an experiment is called a constant. Constants are used to ensure that only one variable is being tested for its effect on the outcome of the experiment.
It is important to only change one variable at a time when doing an experiment, because if you change more than one, there will be uncertainty as to which one affected the result.
if you change more than one variable, you will not know which one has had an effect on the experiment. If the outcome changes when one variable is altered, then the change can only be due to the one variable, by logical deduction.
If you change more than one variable at a time, you will not be able to tell which variable is responsible for what change. Scientists need to know exactly which variable caused the observed experimental results.It is advantageous for scientists to test only one variable at a time during an experiment because if you change all variables at once, you will not be able to tell which variable is responsible for the observed results.

Because if you change more than one variable at a time, you can't tell which is affecting the results.
You only change one variable in an investigation because if you change more than one you won't know which change affected the data.
um varible i think now

It is a matter of certainty. If you change only one variable and the outcome differs, then you may safely assume that the change in the one variable was responsible for that change in outcome. If you change more than one, then how would you know what was responsible? You wouldn't. You would be left guessing. One of the objectives of good science is reduce the guesswork down to as close to zero as possible.
