What is the independent variable answer?
There are two types of variables-independent and dependent. Answer: An independent variable is exactly what it sounds like. It is a variable that stands alone and isn’t changed by the other variables you are trying to measure. For example, someone’s age might be an independent variable.
What is the independent variable in this experiment quizlet?
An independent variable is the variable that is changed or controlled in a scientific experiment to test the effects on the dependent variable. A dependent variable is the variable being tested and measured in a scientific experiment.
Which is the dependent variable in this experiment?
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.
Can gender be an independent variable?
An independent variable is used in statistics to predict or explain a dependent variable. For example, Age and Gender might be used as independent variables to predict the age of death or life expectancy (dependent variables).
What is dependent variable and independent variable in psychology?
The independent variable is the variable that is controlled and manipulated by the experimenter. The dependent variable is the variable that is measured by the experimenter. In our previous example, the scores on the test performance measure would be the dependent variable.
What is an independent variable in research methods?
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 between temperature and time?
So, the temperature depends on the time. So, the temperature is dependent, and the time is independent. If you’re looking at a graph, the independent variable is generally on the horizontal axis.
Why is pressure the independent variable in Boyle’s law?
Boyle’s Law. Gases are often characterized by their volume, temperature, and pressure. These characteristics, however, are not independent of each other. Gas pressure is dependent on the force exerted by the molecular collisions and the area over which the force is exerted.
Is Boyle’s Law direct or inverse?
Boyle’s Law describes the inverse relationship between the pressure and volume of a fixed amount of gas at a constant temperature.
What is Boyle’s Law graph?
The graph of Boyle’s law is known as pressure-volume graph or PV curve. It is as follows: The curve is called PV curve, and it is hyperbolic in nature. As observed from the graph above, pressure increases with a decrease in volume, and vice versa. Thus, pressure is inversely proportional to volume.
