What The one factor that differs between a control group and experimental group in a controlled experiment is the?
When a scientific experiment is carried out in a controlled setting, all variables are kept the same except for the control variable. The control variable is something that is constant and unchanged in an experiment, and is held constant to test the relative impact of independent variables.
When two experiments are identical except for one variable what is that called?
That is called a controlled experiment, where all variables are kept constant except for the one being tested. This helps determine the specific effect of the variable being studied.
What is the difference between a manipulative experiment and a natural experiment?
A manipulative experiment involves actively manipulating variables to observe the effects on the outcome of interest, while a natural experiment relies on naturally occurring variations in variables to study their impact. In a manipulative experiment, the researcher has control over the variables being studied, whereas in a natural experiment, the variables are not manipulated by the researcher. Manipulative experiments are often conducted in a controlled laboratory setting, while natural experiments take place in real-world settings where random assignment is not feasible.
What are the traits that Mendel studied in pea plants easy to predict?
Because they were simple, easy to recognise phenotypes controlled by one set of alleles
Why is it not a bad thing if your hypothesis is rejected?
If your hypothesis is rejected, it means that your experiment revealed valuable information. It allows you to refine your understanding of the topic and design new experiments. In science, rejection of hypotheses is essential for progress and leads to a deeper understanding of the phenomena being studied.
In a controlled experiment what is the experimental group called?
The experimental group in a controlled experiment is the group that is exposed to the treatment or intervention being studied. This group is compared to the control group, which does not receive the treatment.
What is the correct definition for controlled experiment?
A controlled experiment is a scientific study in which one variable is manipulated (independent variable) while all others are held constant, to observe the effects on another variable (dependent variable). The purpose is to determine causation between the variables being studied.

In a controlled experiment a scientist is studying how long it takes parachutes of different sizes to fall to the ground what is the variable?
The variable being studied is the size of the parachutes.
What best describes a property controlled experiment?
A property controlled experiment is a scientific experiment where all variables are kept constant except for the property being tested. This allows researchers to accurately measure the impact of that specific property on the outcomes of the experiment. By controlling all other variables, researchers can confidently attribute changes in the outcome solely to the property being studied.
Does A controlled experiment measures the effect of one variable?
Yes, a controlled experiment is designed to measure the effect of one specific variable while holding all other variables constant. This allows researchers to determine the direct impact of the variable of interest on the outcome being studied.
What is it impossible to perform a controlled experiment on?
It is impossible to perform controlled experiments on phenomena that are unpredictable, uncontrollable, or unethical to manipulate. For example, certain natural disasters, historical events, or intentional harm to individuals cannot be ethically or practically studied through controlled experiments.
Why is a hypotheses so important in a controlled experiment?
A hypothesis provides a testable explanation for the phenomenon being studied in a controlled experiment. It guides the experimental design and helps to focus the investigation on identifying specific cause-and-effect relationships. Additionally, it allows for predictions to be made and tested, leading to meaningful interpretation of the results.
What statement best describes a controlled experiment?
A controlled experiment involves manipulating one variable (independent variable) while keeping all other variables constant, in order to observe the effect on another variable (dependent variable). This allows researchers to determine a cause-and-effect relationship between the variables being studied.
What is the function of the salt solution in this experiment?
The salt solution in this experiment serves to create a controlled environment for testing the effects of salt on the subject being studied. It helps maintain a consistent level of salt concentration, allowing for accurate observations and measurements to be made.
Why are controlled experiment sometimes impossible?
why are controlled experiments sometimes impossible?
What is a controlled expirement?
an experiment that can be controlled i did not know this That is not a good answer! A controlled experiment is: If you set up an experiment: Example: You have two plants. You want to know if fertilizing every day causes it to grow more. In your experiment everything has to be the same! Except one thing. You have to have the same type of dirt and pot and flower/vegetable. You have to water each of them every day. But, you fertilize ONE of them once a day until your results are clear to you, or when you want to stop testing. This way, you can see how the fertilizer effects the plant growth compared to just water every day. If you change more than one thing, like how much you water the plant, it is not a controlled experiment anymore. because then you won't know which variable (thing that you have changed) is taking effect. You wouldn't know if it was more water or the fertilizer, or both that is making the plant grow faster!
