Which of the following is dependent variable?

Which of the following is dependent variable?

The dependent variable is the variable that is being measured or tested in an experiment. 1 For example, in a study looking at how tutoring impacts test scores, the dependent variable would be the participants’ test scores, since that is what is being measured.

What is the dependent and independent variable in Charles Law?

CHARLES’ LAW. – he investigated the relationship between temperature and volume. ▪ independent variable = temperature. ▪ dependent variable = volume. ▪ controlled variables = pressure and number of moles (no gas.

Which gas law involves temperature and volume as variables?

Charles’s law

Is temperature and volume directly proportional?

Key Concepts and Summary The volume of a given gas sample is directly proportional to its absolute temperature at constant pressure (Charles’s law). The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle’s law).

What are the four variables in a gas sample that can be altered?

There are four variables that directly affect the kinetic theory of gases: pressure, temperature, volume and the number of moles.

What are three variables used to describe gases?

Amount of gas (n): Typically measured in moles. Volume: In a closed system, the volume of the gas is the same as the volume of the container. Typically measured in liters. Pressure in a closed system: Typically measured in pascals (Pa) or atmospheres (atm).

What are the four variables?

You can see that one way to look at variables is to divide them into four different categories ( nominal, ordinal, interval and ratio). These refer to the levels of measure associated with the variables. In everyday usage the convention is to then use the level of measure to refer to the kind of variable.

What are the 3 control variables?

An experiment usually has three kinds of variables: independent, dependent, and controlled.

Can age be a dependent variable?

For example, someone’s age might be an independent variable. For example, a test score could be a dependent variable because it could change depending on several factors such as how much you studied, how much sleep you got the night before you took the test, or even how hungry you were when you took it.

What is variable in research with example?

Parts of the experiment: Independent vs dependent variables

Type of variable	Definition	Example (salt tolerance experiment)
Control variables	Variables that are held constant throughout the experiment.	The temperature and light in the room the plants are kept in, and the volume of water given to each plant.
