How are the independent and dependent variables related?

This can get very complicated but, usually dependent variables are functions of independent variables.

It allows you to see the relationship between the variables better than you could in a chart.  You can also find the mathematical relationship by calculating the slope of the graph and determining the equation of the line.

Sorry to say, you better pass on this data set.  \n\nNote that each row of numbers totals 100, as these are percentages, so the variables are correlated, and have limited application.\n\nI think your professor wants two of the variables to be somewhat independent, meaning one is not a function of the other.  Such as gas mileage and price, for example, if you had a list of automobile makes.\n\nRatio variables are those in which the ratio of two of the numbers have meaning, such as miles per gallon, for example.  If car A gets 15 mpg and car B gets 20 mpg, you can take the ratio of the two: 15/20 and compute 0.75, meaning car A gets 75% of the mileage of car B.

I don't know enough about your specific topic but you can express variables in science as ratios or functions of other variables.\nIn order to be specific about how these variables effect and relate to each other you must then be specific about the values of the invariables, or constants as they are more commonly called.\n\nSo .. you should be able to relate and analyse variants in terms of the invariants but without being specific as to the nature of the invariants.\n\nI think that would work.

An example: Boyle's law: pV = constant\nYou choose the volume V (the independent variable)\nWhen you change the volume, the pressure p changes by it: the dependent variable.\npV = constant is only true for constant T, so now the temperature must be the controlled variable; it must be constant.\n\nTh

Two variables are independent if the value of one is not affected when the other is changed. For example,\nIf you have a rectangle, you can change the height without affecting the width, so height and width are independent variables. But, if you keep the height fixed, and change the width, the area of the rectangle will change, so the area and width are dependent variables.\n\nI am going to assuming that you know what an ordinary derivative is. To take a partial derivative, you start with a function of two or more independent variables. You treat all but one of the variables as if they were constants, and then take the derivative with respect that variable.\n\nFor example, if f(x, y) = 6x + 10xy + 12y\nthen to take the partial of f with respect to x, you treat y as if it were a constant and take the derivative with respect to x which gives you \n\n6x + 10y\n\nTo take the partial of f with respect to y, you treat x as if it were a constant, and differentiate\nit as a function of y and get\n\n10x + 12

the independant variable is the one that you can change/control, e.g. time\nThe dependant variable is the one that changes outside of your control. e.g. distance travelled. \nOn a graph you plot the independant variable on the x-axis and the dependant on the y-axis

OH NOES THIS IS LIKE A MATH PROBLEM!!!! i can't handle any more variables :( sry.\n\n\nhahahaha.

Correlation is determining the relationship of one variable to the values of other variables using collected data.\n\nFor example if you considered a person's salary, you might find it correlates with: number of years of education, and number of years of employment, along with other variables.\n\nCross-correlation means a correlation just between 2 variables. You get that expression, because you can evaluate if two variables cross correlate, by plotting one variable on the X and one on the Y axis of a graph. If the cloud of points that result are clustered around a straight line then they cross correlate well.

An Input Variable is something which you put into an experiment - so say a certain amount of chemical you put in being changed.\n\nThe Output Variable is the results you get, which will obviously change.\n\nTom Walvin\nBiology/Chemistry Student

Two events are independent if the outcome of one event does not affect the probability of the second event.  For example: roll a die and flip a coin.  The number that comes up on a die does not change the probability that the coin comes up tails.\n\nTwo events are dependent if the outcome of one affects the probability of the other.  For example:  Pick a gumdrop from a bag containing 3 red and 4 purple gumdrops, eat it, and then pick another one.  If you first pick a red one, it has a prb of 3/7.  But then the prb of again picking a red one would be 2/6 since there are now only 2 reds with a total of only 6.  Hope that helps.

An independent variable is the variable that does not depend on anything, like time.  \n\nThe dependent variable depends on the independent variable.\n\nHere is an example... You want to measure how irritated you get from being around your little brother as a function of time.  Time passes, regardless or your irritability.  But the more time passes, your irritability changes.  So your irritability is dependent on the independent factor of time.\n\nThe control is something that you use to measure experimental values by.  Suppose you are not sure that it is your brother making you irritable... maybe you just become irritable because you are part of the experiment.  So, one day, we measure your irritability as a function of time without your brother.  This is the control.  That way when we measure your irritability with your brother around, we can see how these two differed.\n\nFinally, the constant is something that doesn't change.  Maybe your brother is twice as irritable as your sister.  In this case, irritability is being multiplied by a constant.  Maybe ritalin makes your brother less iritable by a constant amount.  Maybe simply being in the room with your brother, even while he is sleeping, increases your irritability by a certain, constant, amount.

They are not inconsistent. They have a solution (x,y)=(0,4). \n\nThey are not dependent, since one is not a multiple of the other. \n\nThey are independent.

FOR THE MOST PART EQUATIONS WITH VARIABLES LOOK LIKE THIS F(IV)=DV FOR EXAMPLE Y=2X. X IS INDEPENDENT (OR IV IN MY EQ TO THE RIGHT) AND Y IS THE DEPENDENT OR DV THE INDEPENDENT VARIABLE IS THE ONE THAT YOU CONTROL

the degree of the variable is it's power like : A to the power 3\nthen A is a third degree variable....\n                                                                                         bye :)

remember that variables are something that you can change. Your independent variable or manipulated variable is what remains consistent. Your dependent variable is something that you can change throughout the experiment or project. For example if you're doing an experiment plants in which you see if light affects it; the independent variable is the plant. Your dependent variable is what you change or in this case if you put a lamp in the sun and one in the shade. That would be your dependent variable...at least that's what I remembe from science. I might have it backwards...i'm not sure

I think your question have a typo.  There are three variables and I am not sure which one are you trying to solve for.
