Can a chi square ever tell us whether one variable causes variations in the second variable?

Regrettably, no. The most a chi-square statistic can do is to participate in the measurement of the level of association of the variation between two variables.

How do you know whether a relation is a function?
Use the definition of a function. If, for any value of one variable, there is only a single possible value of the second variable, then the second variable is a function of the first variable. The second variable is often called the "dependent variable". If you can solve an equation explicitly for the dependent variable, then it is a function. If you can NOT solve it for a variable, it may or may not be a function - it turns out that some equations are hard or impossible to solve explicitly for one of the variables.
What does it mean if the mean is doubled but the standard deviation is the same?
The second set of numbers are less variable; the coefficient of variation is halved. The second set of numbers are less variable; the coefficient of variation is halved. The second set of numbers are less variable; the coefficient of variation is halved. The second set of numbers are less variable; the coefficient of variation is halved.
How to identify independent and dependent variables in an experiment?
If changes in one variable do not affect the outcome of another variable, then the second variable is independent. A variable that is not independent is dependent.
What is the ordered pair in an equation?
(x,y) or (variable that cones first in the alphabet, variable that comes second in the alphabet)
What is a variable to the second power called?
A variable raised to the second power would be refered to as "squared." Some math-based programs like Excel let you enter a power with a carot, ie, "(variable name)^2" if you want to calculate the answer.

Math tell whether the ordered pair is a solution of the equation?
The idea is to replace one variable in the equation by the first number in the ordered pair, the other variable with the second number in the ordered pair, do the calculations, and see whether the resulting expressions are indeed equal.
What does a rate of change indicate?
The rate of change indicates the change in one variable per unit change in a second variable at (or around) that level for the second variable.

What does a bar graph display?
Each bar displays the value of one variable for one value of a second variable. The second may be a qualitative variable or a quantitative one.
What is the difference between a fixed second mortgage and one with a variable rate?
The difference between a fixed second mortgage and one with a variable rate is that fixed second mortgage has a fixed rate and is commonly thought of as safer than a mortgage with a variable rate.

What does 320kbps variable bit rate mean?
The bit rate is the amount of data the file uses per second in kilobits. Higher bit rate does not always mean better quality just more data. A 320kbps constant bit rate song means every second of the song consists of 320kilobits A 320kbps variable bit rate song means on an average the song contains 320kilobits for every second of the song. The more complex portions of the song are encoded using more bits per second, the less complex portions with fewer bits per second. For example, a 10 second duration which contains very smooth variations in the amplitude can be encoded using lesser bits; whereas another 10 second duration with extra-fast variations in the music would be encoded using more bits so as to retain more information - thereby giving better fidelity. This is the advantage of a variable bit rate song. On the other hand, variable bit rate songs are more complicated to encode and decode; so getting your media player to play variable bit rate songs usually forces the decoder and associated software/hardware modules to work at their peak.

How do you assign value of one variable to another variable in unix?
If you are asking about shell usage, just assign the value as follows: first=5 second=2 first=$second
