All values that arise as influenced by changes in the values of other variable. Or, Dependent Variable is the observed factor.
If we have a Linear Function as
Y = mX + C
so,
Y should be Dependent Variable,
X as Independent Variable,
m as Coefficient and
C as Constant.
The responding variable is another name for the dependent variable.
On a graph, the x variable is the independent variable and the y variable is the dependent/responding variable.
I remember the difference between the two in that the dependent variable depends on the independent variable. For example, for teenagers, in height versus age, the age would be the independent variable and the dependent variable would be the height. We would expect as teenagers get older, they are taller.
Independent means that it does not depend on, does not rely on, is not affected by anything. A dependent variable is a variable is affected by some other variable. If. the independent variable happens to change its value, the dependent variable must comply and change also according to the rule that connects the two variables.
An example of independent variable is time. It runs its course, not affected by anything else. Maybe a money example will be more transparent.
Suppose you have a part-time job to support you in your studies. In a part-time job, the number of weekly work hours is not fixed in advance. Some weeks you are relatively free and can work more hours. Other weeks you have exams and can't do as much.
Let us consider the situation: your weekly salary. You understand that your weekly salary will vary in relation to the total number of hours you work during a given week. The more you work, the more you earn. The less you work, the less you earn. Clearly there is a link between the number of work hours, and the weekly salary. You have two quantities that vary from week to week. They vary: so they are called variables (variable= capable of varying/changing its value).
The two variables are x= number of hours worked in a given week, and y= weekly salary earned in the same given week.
You and only you can decide of your own free will on the number of hours you will work that week. However, once you choose/decide how many hours you will work, your salary is calculated according to a set rule your boss and yourself had agreed to.
Of the two variables in the situation describing you weekly salary, the number x of hours worked is the independent variable. The weekly salary y is the dependent variable: the amount of money you get depends on/ is decided by the number of hours you worked.
Please use a dictionary to see the meaning of the verb to depend on, and the adjectives dependent, independent.
Dependent variables are the output of certain actions or variations in the independent variables. In this case, the dependent variable would be the sludge you create. The water would be a constant medium to the independent variables grits,salt, and pepper
When conducting an experiment, a researcher usually has a dependent and independent variable. The independent variable is the variable that can be changed or manipulated (think of it as a cause). The dependent variable is the variable that depends on the independent variable (think effect).
For example, if you wanted to test whether or not taking Advil affects the length of a headache:
Taking Advil (or not) is what you can manipulate. It is the independent variable.
Headache duration is the dependent variable. The results depend on whether or not Advil was taken.
When conducting an experiment, a researcher usually has a dependent and independent variable. The independent variable is the variable that can be changed or manipulated (think of it as a cause). The dependent variable is the variable that depends on the independent variable (think effect).
For example, if you wanted to test whether practice improves an athlete's performance (lets say number of touchdowns):
Practicing (or not) is what you can manipulate. It is the independent variable.
Number of touchdowns is the dependent variable. The results depend on whether or not the athlete practiced.
for a full definition, try wikipedia. an independent variable can be freely changed. a dependent variable will BE changed as the independent variable is changed basically there are 2 main examples. mathematical, and experimental.
with experiments,(science, chemistry etc.) one example would be changing the amount of fertilizer fed to a plant to see how it affects growth. there are 2 variables here. amount of fertilizer used and growth of the plant. the amount of the fertilizer can be freely changed. (independent variable) the amount of growth DEPENDS on the amount of fertilizer (dependent variable)
with maths, you can use something like 2x+5=y. x can freely changed. it is the independent variable. y will change depending on the value of x.
