Which paper towel brand is the strongest independent variable?
Bounty
What is the independent variable to be tested in this experiment?
The independent variable (IV) is the characteristic of a psychology experiment that is manipulated or changed by researchers, not by other variables in the experiment. For example, in an experiment looking at the effects of studying on test scores, studying would be the independent variable.
What is the independent variable in a lab?
The independent variable is the factor changed by the person doing the experiment. This is the one you manipulate or vary during the experiment. The dependent variable changes in response to the independent variable. It is the one that is measured by you during the process of the experiment.
What is independent variable in Aba?
Independent Variable: the variable that is systematically manipulated by the researcher in an experiment to see whether changes in the independent variable produce reliable changes in the dependent variable. In ABA, it is usually an environmental event or condition antecedent or consequent to the dependent variable.
How do you identify the independent and dependent variables?
Independent and dependent variables
- The independent variable is the cause. Its value is independent of other variables in your study.
- The dependent variable is the effect. Its value depends on changes in the independent variable.
What is the independent variable in the gummy bear experiment?

Is temperature a independent variable?
An independent variable is one that is unaffected by changes in the dependent variable. For example when examining the influence of temperature on photosynthesis, temperature is the independent variable because it does not dependent upon photosynthetic rate.
Is Boyle’s Law direct or inverse?
The law itself can be stated as follows: For a fixed mass of an ideal gas kept at a fixed temperature, pressure and volume are inversely proportional. Or Boyle’s law is a gas law, stating that the pressure and volume of a gas have an inverse relationship.
What is Boyle’s law in simple terms?
: a statement in physics: the volume of a gas at constant temperature varies inversely with the pressure exerted on it.
What are the assumptions of Boyle’s Law?
The assumptions made in Boyle’s law are the constant temperature and number of moles of gases or amount of gas, the gas is within a closed system and lastly, the gas behaves ideally. An ideal gas is defined as a theoretical gas whose interactions are perfectly elastic collisions following the ideal gas law
What is Charles and Boyle’s law?
Boyle’s law—named for Robert Boyle—states that, at constant temperature, the pressure P of a gas varies inversely with its volume V, or PV = k, where k is a constant. Charles (1746–1823)—states that, at constant pressure, the volume V of a gas is directly proportional to its absolute (Kelvin) temperature T, or V/T = k.
