The degrees of freedom are the number of extra numbers you need to specify your data completely, after you have provided a summary of your data.
Example: You have ten numbers. You also know that the mean is 1.3 and the standard deviation is 0.6. Since ten numbers were required to describe your data completely and you already have two, the degrees of freedom are 102=8.
This is an important concept when doing statistical tests. For example, suppose you have a 2x2table and you want to apply the chisquare test for independence between rows and columns. The chisquare test is based on the assumption that you already know 3 numbers: the row proportions, the column proportions and the totalt number of observations. Since the total number of number in your table is 4, and 3 were already known before you started to compute the chisquare statistic, the degrees of freedom is 43=1. Now the theory says that you must use the chiquare table with one degree of freedom.

A debenture is a type of debt instrument that is not secured by physical asset or collateral. Debentures are backed only by the general creditworthiness and reputation of the issuer. Both corporations and governments frequently issue this type of bond in order to secure capital. Like other types of bonds, debentures are documented in an indenture. A debenture is basically an unsecured loan to a corporation. Often there is a provision to exchange this debt for corporate stock. Nonconvertible debentures do not have this provision. A mortgage represents a loan or lien on a property/house that has to be paid over a specified period of time. Think of it as your personal guarantee that you'll repay the money you've borrowed to buy your home.

Degrees of freedom are the unrelated variables involved in whatever you are testing. For example, if we were correlating age with height and weight we would have 3 degrees of freedom.

Degrees of freedom is used to minimize the error of the results in statistics. That is why it is called degrees of freedom.
Degrees of freedom: The maximum number of quantities whose values are free to vary before the remainder of the quantities are determined.

Stats tries to predict a number out of past data. For example, if we think the number is 10, 'Give or Take' 4. The give or take part is the degree of freedom.

The "degrees of freedom" are the independent pieces of information needed to exactly specify the state of a system. For instance, a particle moving in three dimensional space has 6 degrees of freedom.
Three numbers are needed to describe the position of the particle in space. (The x, y, and z coordinates do nicely.) Another three numbers are required to specify the velocity of the particle. (The components of the velocity vector in the x, y, and z directions for instance.) Thus, we need 6 numbers to exactly describe the particle's state.
There are many other situations where we can talk about "degrees of freedom". For instance, we may be studying the relationship between age, sex, and college GPA in a population. In this situation, we have three "degrees of freedom" for each person.
