I'm thirteen so don't be embarrassed if i know it and you don't. ( no offense) The three types of variables in scientific inquiry is Independent variable Dependent variable Control variable

Variables in the scientific method are elements that can be changed or controlled in an experiment to test their effects on other variables. They are typically classified into three types: independent variables, which are manipulated by the researcher; dependent variables, which are measured in response to changes in the independent variable; and controlled variables, which are kept constant to ensure that the results are due to the manipulation of the independent variable. Properly identifying and managing these variables is crucial for obtaining valid and reliable results in scientific research.
In scientific investigations, three key types of variables are independent variables, dependent variables, and controlled variables. The independent variable is the factor that is manipulated or changed by the researcher to observe its effect. The dependent variable is the outcome or response that is measured to assess the impact of the independent variable. Controlled variables are those that are kept constant throughout the experiment to ensure that any observed changes can be attributed solely to the independent variable.
The three parts of a hypothesis are to identify the problem, make an educated guess and identify the major variables. A hypothesis is the description of a scientific question.

There are three types of variables tested: manipulated variables, controlled variables, and experimental variables.
Independent Variables, Dependent Variables and Extraneous Variables.
A variable is something that does not have a fixed value. Its value varies.So three examples might be:1. Your weight (it does not stay absolutely constant)2. The price of something such as a bottle of coke.3. The temperature.

The three demographic variables commonly used are age, gender, and income. These variables help categorize and identify characteristics of a population for research and marketing purposes.
