It is done in a systematic manner where the observer designs a systematic procedure for identifying, categorizing and recording in a natural or staged behaviour.

In this paper we have illustrated the basic techniques of statistical analysis and hypothesis testing relating to a real-world business problem. This analysis helps the company management to better understand the production strategy. It was found that there is a strong association between height of the student and his (her) shoe size.

Summary

In this paper we have discovered the basics of descriptive statistics for statistical data of temperatures in the pots. It was determined which pot has the highest temperature on average and which has the lowest. The basic characteristics of temperature distribution (measures of central tendency and variability) for each section were given. One-sample and Two-sample Student’s t-test were applied to check the difference in AlF3 calculations methods and the amount of cryolite used in manufacturing process. It is appeared, that old and new calculation systems are significantly different from each other. Also, the hypothesis of plant management about Continue reading...

According to McFerran in the ”A Dictionary of Nursing,” plastic surgery is “the reconstruction of parts of the body deformed or damaged by burns, major accidents, or cancer” and birth defects. In the Oxford Dictionary of English, plastic surgery refers to “the process of reconstructing or repairing parts of the body by the transfer of tissue, either in the treatment of injury or for cosmetic reasons”.

ABSTRACT

The imposition of the death penalty does not deter crime because statistics revealed a contrary effect and studies pointing to deterrent effects have been proven to be inconclusive. The lifting of the moratorium on the death penalty in 1976 by the United States Supreme Court largely stemmed from the work of an economist, who, with the use of econometrics concluded that every execution saves about 8 lives. A scrutiny of Uniform Crime Research statistics revealed, however, facts that would seem to disprove the contention of this research and others like it. Not only most of the states with no Continue reading...
