What else can I help you with?
Does a controlled experiment have only one variable?
No, a controlled experiment can have more than one variable. However, in a controlled experiment, only one variable is intentionally changed (independent variable) to observe its effect on another variable (dependent variable), while all other variables are kept constant (controlled variables) to ensure the validity of the results.
Something that causes changes in an experiment?
The factors that can influence the course of a reaction are known as variables and or sources of error. Experiments and testing seek to control these variables, errors and account for them to ensure quality and safety of their results.
To ensure that an experiment is testing only one variable scientists often run a?
controlled experiment where all variables are kept constant except for the one being tested.
When a n experiment shows that two variables are closely related the experiment shows?
that there is a strong correlation between the two variables. This means that as one variable changes, the other variable is likely to change in a consistent way. This correlation can suggest a cause-and-effect relationship between the variables, but further research is needed to establish causation.
What is a summary of what you learned from a experiment?
From an experiment, I learned that changing the independent variable can have a direct impact on the dependent variable. The results may support or reject the hypothesis, providing insights into the relationship between the variables being studied. Additionally, controlling variables and conducting multiple trials help ensure the reliability and validity of the experiment's findings.
What are things in an experiment that change or could be changed are called?
variables
What factor is not changed in a experiment?
The controlled variables.
How it calls the part of the experiment where no variables have been changed?
The control
What are variables that remain the same in a scientific experiment?
Variables that remain constant in a scientific experiment are called controlled variables. These variables are not changed throughout the experiment to ensure that any observed effects are due to the independent variable being tested.
What is purpose of having a control in a experiment?
Having a control in an experiment allows you to see what happens when no variables are changed. If you do not have a control, you do not have anything to compare your results with after changing variables of the experiment.
The variables in an experiment that stay the same?
These "variables" are called independent variables or constant variables meaning that they are capable of being changed by the experimenter but are intentionally held the same through each individual experiment.
Are control variables those that are changed in an experiment?
No, control variables are not the ones changed in an experiment; rather, they are the factors that are kept constant to ensure that any observed effects can be attributed to the independent variable. By controlling these variables, researchers can minimize their influence and isolate the relationship between the independent and dependent variables. This helps improve the reliability and validity of the experiment's results.
How can AN EXPERIMENT that disproves a hypothesis be used?
by the variables. The variables are manipulated and responding. the manipulated ones are the one that is changed in the experiment. the responding variable is the one who is expected to change.
How can an experiment that disproves hypothesis be useful?
by the variables. The variables are manipulated and responding. the manipulated ones are the one that is changed in the experiment. the responding variable is the one who is expected to change.
The factor in an experiment that is changed by the experinenter is the?
A scientific experiment must be done by something that can show change. All of these can be variables.
What are constant variables and y r they important in an experiment?
. Constant variables are variables which cannot be changed with the experiment. To remember their name is easy just think about Constance. They are important to an experiment because without all three variables there would be no complete experiment. Also the constant variables are important to an experiment because they help complete the result. Without a constant variable you. Would not be testing correctly
Can you change an independent variable?
Yes, independant variables are the variables that are changed in an experiment to observe the results, called the dependant variable.
