Graphical Representation of Data Chapter 3 ☞ (Paste Examples of any graphs‚ diagrams and maps showing different types of data. For example‚ relief map‚ climatic map‚ distribution of soils maps‚ population map) REPRESENTATION OF DATA Besides the tabular form‚ the data may also be presented in some graphic or diagrammatic form. “The transformation of data through visual methods like graphs‚ diagrams‚ maps and charts is called representation of data.” The need of representing data graphically:

scientific research because they allow the researchers to analyze empirical data needed to interpret the findings and draw conclusions based on the results of the research. According to Portney and Watkins (2009)‚ all studies require a description of subjects and responses that are obtained through measuring central tendency‚ so all studies use descriptive statistics to present an appropriate use of statistical tests and the validity of data interpretation. Although descriptive statistics do not allow

In this essay the concepts of empiricism and empirical methods and their use in geography will be critically discussed. The main points that will be discussed include the origins of empiricism‚ what empiricism means‚ why empiricism might be useful‚ what empirical methods are‚ the advantages and disadvantages of empirical methods‚ how they are applied in geography including examples and the benefits of applying these in geography. Starting with the origins of empiricism‚ Aristotle was the first

Enthalpy vs. entropy (h-s) 6. Pressure vs. enthalpy (P-h) The term saturation temperature designates the temperature at which vaporization takes place. For water at 99.6 C the saturation pressure is 0.1 M Pa‚ and for water at 0.1 Mpa‚ the saturation temperature

Question 1 How can graphics and/or statistics be used to misrepresent data? Where have you seen this done? Answer: It is a well known fact that statistics can be misleading. They are often used to prove a point and an easily be twisted in favor of that point. Statistics‚ graphics and database are used in medical field to approve‚ prove or disapprove theories‚ analysis and interpretation of ailments‚ medications and its impact and treatment and its effectiveness. As noted by Nursing Research (2011)/

Graphical and Simplex Methods of Linear Programming The graphical method is the more popular method to use because they are easy to use and understand. Working with only a few variables at a time they allow operations managers to compare projected demand to existing capacity. The graphical method is a trial and error approach that can be easily done by a manager or even a clerical staff. Since it is trial and error though‚ it does not necessarily generate the optimal plan. One downside of this
