Data analysis is a group of techniques that facilitates in illustrating facts, identifying patterns, building on justifications, and examining hypotheses. It is employed in every part of the sciences and is applied in business, organization, and guiding principles (Levine, 1997, p. 1). The mathematical outcomes supplied by a data analysis are mostly basic and simple. It comes across the figure that portrays a representative value and it realizes differentiations among figures.
Data analysis gets hold of averages, such as the average earnings or profits, and it comes across divergences such as the discrepancies in earnings from group to group or from period to period (p. 2). Basically, the arithmetical solutions made available by data analysis are that simple. However, data analysis is not all pertaining to figures—it makes use of them. It is with reference to the world, inquiring constantly of “How does it work? ” That is where data analysis becomes complicated. As a hypothetical example, Sharma (1996) asserts that between 1790 and 1990, the US business profits grew by 245 billion, from 4 billion to 249 billion U.S. dollars.
Those are the details; nevertheless, if it were to be accounted for, those figures and facts that the population increased at an average pace of 1. 2 billion U. S. dollars annually, 245 billion dollars divided by 200 years, the information would be incorrect. The information would be accurate and the numerical items would be proper if it were stated that 245 billion dollars divided by 200 years is more or less 1. 2 billion dollars per year. On the contrary, the explanation “increased at an average pace of 1. 2 billion dollars annually” would be erroneous. The U. S. business profits did not expand that manner, not even almost.
So what should a practitioner do with a tricky dilemma? This may be the most significant point that is taught in data analysis: Logic would convey that a practitioner would embark upon a complicated dilemma with a complex method. It would as well impart that the most excellent data analyst is the person with the prevalent knowledge of intricate “high power-driven” procedures. However, logic is incorrect on both statements. In data analysis, the actual “trick” is to make the trouble simpler and the finest data analyst is the person who accomplishes the task well, with the easiest techniques.
A journal cited in academic behavioral research written by Vancil (1997) states that the rules of data analysis are the following. First is to observe the facts, reflect on the facts, contemplate on the predicament, and inquire what is needed to be recognized. The focus of finding must be mulled over. On the contrary, thinking is the principal action but the most frequently skipped over as if, by some means, human interference in the progressions of science were a hazard to its independence and to the firmness of the science.
Nevertheless, no, contemplation is necessary. A practitioner is supposed to understand and unravel verifications in terms of his or her own experience. He or she is required to weigh up facts in terms of his or her preceding outlooks (and he or she had better have a number of prospects). The practitioner is obliged to consider the information in terms of terms and assumptions, even supposing the terms and assumptions may turn out to be mistaken.
The second rule is to approximate the Central Tendency of the Data. The “central tendency” can be regarded as a simple average or mean. Nevertheless, it can also be somewhat more difficult such as a pace. An example is that the growth rate of the U. S business profits is two percent yearly. Moreover, why would a practitioner have considered approximating a thing as detailed as a scale of growth? The answer is that he or she thought as regards the information, the dilemma, and about where he or she was heading.
