Frequency Distribution help

Posted on March 17th, 2011 — Posted in Assignment help

Statistics applies various tools, techniques and methods of analyzing sets of data. One of the terms frequently used in statistics is frequency distribution. What does it imply? Frequency distribution implies compilation of tables, which contain statistical values taken by the suggested statistical variables.

Frequency distribution is represented in the forms of tables or graphics that show different empirical observations in the required intervals, which are supposed to be reciprocally exhaustive and exclusive. Each student who is given the assignment in statistics, which involves frequency distribution, should remember that the range of the interval depends upon a number of factors, including the aim of the statistical analysis and the analyzed sets of statistical data. It is also worth mentioning that intervals should never overlap, but contain different statistical observations.

Frequency distribution finds its application not only in statistics or mathematics, but in financial spheres as well. For example, its tabular variant is often used by the investors to define the stock returns for the specified period of time and to determine possible fund risk they may face. It should be mentioned that frequency distribution reflects either the percentage of the given statistical observations or their exact number. If it manifests the percentage of statistical observations, the frequency distribution is referred to as “relative distribution”.

If you are struggling with your frequency distribution homework yourself, you should keep in mind that frequency distribution may be represented by different graphical means, including ordinary statistical histograms, relative and density frequency histograms as well as accumulation curves. Histograms reflect frequency units, which are defined within the value set, whereas accumulation curves demonstrate frequency units, which exist below the suggested statistical value.

We may also differentiate between univariate frequency charts and joint frequency distributions. Univariate statistical frequency charts are typically organized in the form of enlisted points, which reflect how often this or that statistical value occurs. Joint frequency distributions, in their turn, are frequently represented as bilateral contingency squares or charts that involve marginal frequencies.

Students, who require professional help in solving their frequency distribution tasks, may apply for highly qualified online assistance. Experienced homework solvers are always ready to offer accurate solutions according to your deadlines and specifications.
