The y-Variable
An independent variable can be any of a given set of values while a dependent variable is represented as a function of another variable.
An independent variable is a variable that isn't affected by something else. A dependent variable is a variable that's affected by changes in the independent variable.
Independent variable is time; dependent variable is temperature.
In cases wherethe dependent variable can take any numerical value for a given set of independent variables multiple regression is used.But in cases when the dependent variable is qualitative(dichotomous,polytomous)then logistic regression is used.In Multiple regression the dependent variable is assumed to follow normal distribution but in case of logistic regression the dependent variablefollows bernoulli distribution(if dichotomous) which means it will be only0 or 1.

the set of values of the dependent variable for which a function is defined
Independent variable is time; dependent variable is temperature.
using a variable resistor we can adjust the sensitivity of a light dependent resistor
The experimenter decides on a set of values for the independent variable, then measures the value of the dependent variable for each one.

Depends on the experiment - there may be no relationship. Typically proportional, inversly proportional, proportional to the log and similar are given in set experiments at schools. So a staight line going up and straingt line going down or a curve of some sort when drawn as a line graph.
The independent variable is the one factor that will be manipulate or changed during the experiment....The dependent variable is the variable that becomes altered as a result of the change that was made in the independent variable...
An independent variable is the variable of the experiment that the dependent variable depends on. For example, in an experiment testing the effects of soil quality on a plant's growth, the dependent variable would be the plant's growth and the independent variable would be the quality of the soil.
The dependent variable in this experiment is the number of animals caught in the pit traps after three days.
