The independent variable causes changes in the dependent variable; the dependent variable is contingent on the manipulations of the independent variable.
An intervening variable is an internal state that is hypothetical in empirical research. It explains the relationships between variables being observed.

i dont't know them all but i hope this helps: - categoric variables: these are the variables that have values that fall into categories and have labels. eg. types of metal - continuous variables: these can have any number or value. eg. the temperature in a room. always plot this type of variable in a line graph. - discrete variables: the values of these variables are definite numbers, and are not continuous. eg. size of shoes- can only be in sizes and half sizes. i hope this is some help :D
A dependent variable is a variable that you (the experimenter) do not change. It changes in response to the Independent variable, which is what you change. For example: Say I was growing two plants and I wanted to see how they would grow dependent upon how much light they received; I would have one in the dark and one in natural light. The independent variable is how much light they received, and the dependent variable is how much they will grow in response to how much light they get.
If x depends on a, b and c, then x is the dependent variable, and a, b, and c are the independent variables - you can vary them at will, and x depends on them. Often it appears on the right hand side of an equation, such as x = a +b + 2/c, showing how x depends on the independent variables.
An independent variable is the variable you can change in an experiment. On a graph, it's on the X-axis. A dependent variable is the result of changing the independent variable. It is literally dependent on it. The dependent variable goes on the Y-axis.
The y variable! It may be one of the dependent variables.

A bar graph.
The variable YOU change which will in turn effect another variable (the dependent variable). The controlled variable is plotted on the x - axis of a graph.
No. It shows changes in the response variable against changes in the explanatory (or independent) variable(s).

a simple 2d xy line graph has only the possibility for 2 different variables (x and y). for a 3 variable graph you would have to go into a 3d xyz graph with each variable as x, y and z. it is possible to fit a line to this but for an easier analysis it is better to analyse the variables in pairs.
The steps are to find the y-axis (dependent variable) and the x-axis (independent variable), then make a scale for your variables on the graph.
Select any value for one of the variables in the graph and solve the equation to get the other variable.
To illustrate the relationship between one or more dependent variables and a variable (often an independent variable).
It is a visual representation of changes in the values of two variables. The graph does not show causation.
