Medicine A will reduce the incidence of headaches . what is the independent variable and dependent variable and the two controlled variables?
What are two controlled variables of fertilizer in soil increases flower production
Medicine A
i dont know
To identify the independent variable, dependent variable, and controlled variables in this scenario, we need to understand the basic components of an experiment.
1. Independent variable: This is the factor that the researcher manipulates or changes deliberately. It is the variable believed to have an effect on the dependent variable. In this case, the independent variable would be the medicine being administered (Medicine A).
2. Dependent variable: This is the outcome or response that is being measured or observed. It is the variable that is expected to change as a result of the manipulation of the independent variable. In this case, the dependent variable would be the incidence of headaches.
3. Controlled variables: These are the factors that remain constant throughout the experiment and are not allowed to change. Their purpose is to eliminate any potential confounding variables that could affect the outcome besides the independent variable. In this scenario, two controlled variables could be:
- Dosage of the medicine: To ensure consistency, the dosage of Medicine A should remain the same for all participants.
- Population/sample size: The experiment should ideally be conducted on a homogeneous group (e.g., same age, gender, health conditions) to minimize confounding factors.
By controlling both the dosage of the medicine and the participant population, researchers can better isolate the relationship between Medicine A and the incidence of headaches.
An independent variable is the potential stimulus or cause, usually directly manipulated by the experimenter, so it could also be called a manipulative variable.
A dependent variable is the response or measure of results.
Extraneous variables — other than the independent variable — potentially can affect the dependent variable, so they must be controlled. If possible, you try to keep them constant between the experimental and control group.
The experimental group receives the independent variable.
The control group is similar to experimental, except it does not receive the independent variable. Extraneous variables are balanced between experimental and control groups.
From this information, you should be able to determine the independent and dependent variables. You have not mentioned any other variables that might need to be controlled. However, gender and age might fit.
