Chance association, (the relationship is due to chance) or causative association (one variable causes the other).

Why should outliers generally be excluded when interpreting the relationship of the variables?
The assumption in the question is not valid. There are two main reasons for outliers: one is that there is a measurement or recording error and if that is the case, then the outlier should be excluded. However, it is possible that the model under consideration is no longer valid when you get near the outlier.
What does a line graph in which the data points do not fall along a straight line mean?
There are several possible answers: The line is actually meant to be a curved line and not a straight line. The relationship between the two variables is not a linear function. Discovering this can be one of the main reasons for drawing the graph. The data points are empirical measurements (from an experiment, for example) and there are errors associated with the observations. The errors may be systematic or random. You have made mistakes - either in recording the data or in plotting them.

What are the advantages and disadvantages using broken line graph?
A broken line graph is useful when there is a large gap between the values of one of the variables. In the context of graphs over time, this may happen for many reasons. Possible causes are that the data were not available for a period (eg during war), or the method of collection was changed. Nevertheless, if these breaks are explained, the graph can provide indications of long term trends. The disadvantage is that data on either side of the break, may not be comparable, even with the explanations, and the naive or careless user may be misled.

What is Multiple Correlation?
Let me assume that you are familiar with the (Pearson) correlation coefficient. If you estimate how one variable might be a linear function of another (using least-squares) then the measure of how strong the association is is known as that with which you are correlation coefficient. If you generalise by estimating what linear function one variable is of two or more other variables then the measure of how strong the relationship is is the multiple correlation.For mathematical reasons which may or may not interest you, and which I won't go into here, if we now go backwards we find that the multiple correlation for the situation where one variable is regressed against one other variable is just the square of the Pearson correlation coefficient.As you probably know, the Pearson ranges from -1 to +1. Because the multiple correlation is the squared value it ranges only from 0 to 1 and can indicate only degree of association, not the sense of direction.
Will sucking nipples during sexuality causes breast cancer?
No. Babies (and husbands) suck them all the time, although for different reasons. There is a VERY SLIGHT correlation between nursing and SLIGHTLY lower rates of Breast cancer, so let them suck away! That's what they were meant for.

What is meant by delare or initialize a variable or constant at a lowest possible level?
It probably refers to "scope" (see http://en.wikipedia.org/wiki/Scope_(programming)). In programming languages with lexical scope, variables declared in an outer scope can be used in an inner scope, but variables declared in an inner scope cannot be used in outer scopes. It is considered best practice to declare variables (and constants, which are just variables that don't change) at the innermost scope possible for several reasons: # It makes it most clear what the scope of use is of the variable. # It makes it impossible to mistakenly use it in some other location. # It makes it easier to keep track of what variables exist at any given point in the code. For example, in standard C, nested functions are not allowed. This means that in any function, only two types of variables exist - global variables, and variables declared within that function. This has the advantage of making it easy to understand what any variable refers to.

Why do boys burp with there friends and not with there girlfriends?
There are multiple reasons why, and to start we will remove anything that is "learned", as that would be too restrictive to individual people.Generally speaking, a man will not belch in front of a girlfriend/significant other for one of two reasons.Reason 1: As a form of respect to their significant other.Reason 2: In an attempt to appear as civil and attractive as possible, no matter if it is "true" to themselves or not.NOTE: There are exceptions to near every rule, and there are many to this one. The two reasons I gave are two complete opposite ends of the spectrum, and there will be variables associated with every situation which will have other reasons between the two I listed.
