What is the relationship between the dependent and independat variables?
dependent = y values, independent = x values
How are constants and variables different?
Constants are values that remain constant and cannot be changed once they are assigned a value. Variables, on the other hand, can have different values assigned to them and their value can be changed throughout the program. Constants provide a fixed value, while variables provide flexibility and allow for changes in value.
In an experiment dealing with distance versus velocity which is the independent variable?
It will depend on the experiment. The answer is unclear because the question was not specific enough. There are experiments where either can be the independent variable. Your question is a bit vague, but there might be a solution. The best solution would be if you had your raw data, or remembered the structure of the experiment. Were you measuring velocity at specific distances, or were you measuring distances from set velocities? The set/specific values are your independent variables, and therefore the other quantity depends upon what you measured at those set intervals. The other possibility is in the wording of the question. If it is from your teacher, it is likely that the distance is the independent variable, as older terminology for graphing that uses versus, implies (not a guarantee, see below) that the independent variable is first (versus) the dependent, or x vs. y. Since the question states distance vs. velocity it can be assumed (again, not a guarantee) that distance is the independent and velocity is the dependent. You should ask for clarification of the whole versus phrasing, as some people don't know the order, and it is confusing. For example I had a high school teacher (and many other teachers) who stressed independent vs. dependent when graphing, because x comes before y. I had a college professor who stressed dependent vs. independent as the wording, because slope is y over x. So which is it, is the question; therefore it really is a poor way of describing the graph of the data. Regardless of which word goes before the versus, the independent is graphed on the x-axis, and the dependent is graphed on the y-axis. Next time ask for clarification phrased as _________ as a function of ___________. The first blank is of course the dependent variable, and the last blank is the independent variable.
Which two variables determine the gravitational potential energy of an object?
The formula for potential energy is PE = mgh (mass x gravity x height), so it depends on those three values.
What are different ways data can be graphed from experiments?
It depends on what you are trying to represent. Here are some:x-y plot, where typically the independent variable is the horizontal axis, and the resulting measurement at particular values of the independent variable are plotted on the vertical. Example would be position (vertical) vs time (horizontal), or amount of expansion (vertical) vs temperature (horizontal).Histogram or bar-chart, where the data is categorized by some critieria, and the amount in each category is vertical. As a bar chart the categories could be anything - colors, species, seasons. In a histogram, the categories are ranges of values (ages, frequencies in a spectrum, etc.)Pie chart is useful to show the proportion or percentage of each measurement as related to the whole. Here are some links, that may help.http://www.mathsisfun.com/data/histograms.htmlhttp://nces.ed.gov/nceskids/createAgraph/

How are the independent and dependent variables related?
Independent variables can take values within a given boundary. The dependent variable will take values based on the independent variable and a given relationship at which the former can take its values.

What is the relationship between the dependent and independat variables?

What is an experimental variable?
A variable whose values are independent of changes in the values of other variables. The factor you are testing.

Why are function notation important?
A function is a relationship between quantities (variables) that occurs when the value of one of the quantities can be given uniquely by specified values of the other quantities. The variables involved can be either independent or dependent. The values of certain variables are fixed while others are allowed to change. The fixed variables are called the independent variables, and the dependent variables are those that change in response to the given value of the independent variable. A function therefore relates dependent variables to independent variables, the only restriction being that each value of the dependent variable is given uniquely by one, and only one, value for each of the independent variables.

experimental control
Can independent variables be changed?
Yes. In fact, in multiple regression, that is often part of the analysis. You can add or remove independent variables to the model so as to get the best fit between what values are observed for the dependent variable and what the model predicts for the given set of independent variables.
What is the definition of domain used in math?
the set of possible values of the independent variable or variables of a function.
The difference between the independent and dependent variables?
Independent variables are variables that can be changed in an experiment, while dependent variables are variables that change as a result of an experiment. In other words, independent variables are what you change, and dependent variables are the results of the experiment.
