Data Collection Instruments

Direct Observation
This method is used where the observer wishes to directly observe how activities are done, how people behave or the frequency in which certain things occur (Weaththington, Cunningham and Pittenger, 2010). It can also be used to determine self-control, truthfulness, honesty and cooperativeness of people when they are doing certain activities. 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. By natural behaviour we mean that the observer does not plan to follow a certain way of directly observing the way Continue reading...

Summary

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. The approximation model was constructed to make forecasts of shoe size with given height of a student. It also appeared that the sizes of shoes of men and women are significantly different. That’s why the company can’t produce one type of sport shoes for both Continue reading...

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...

Statistical Test Proposal

Enabling accuracy in research findings requires the appropriate use of statistical tools to synthesize the collected data. For this problem oriented policing field test study, the chosen approach is the mixed methodology, which encompasses the use of both qualitative and quantitative methods. As such, the use of statistical tools is essential in drawing out the findings of the POP field test study. Descriptive statistics will be the primary tool to use in interpreting the gathered data.

Definition of Descriptive Statistics

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”. Presumably, when a person seeks plastic surgery to fix a deformation after an accident or battled illness, societies will offer their support. After all, the plastic surgery in such cases attempts to reconstruct Continue reading...

Introduction
What is a Radiologi Technologist?
A radiologic technologist performs diagnostic imaging examinations on patients. He/she specializes in x-ray, Cat scans, and computed tomography (CT) imaging. He/she also administers non-radioactive materials into a patient’s blood stream and interpret the resulting image/s. Some radiologic technologists make a medical mixture for the patient to drink that enables soft tissue to be seen and evaluated as clear images by the radiologist. Technologists may also be certified in multiple specialties, such as mammography. They may also specialize in geriatrics or pediatrics or they make work on ultrasound, magnetic resonance, or computed tomography. Continue reading...

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...

Abstract

Sexual assault or rape is a serious crime that has long-lasting effects on the victim of the assault as well as everyone around them. The numbers of these crimes that occur in colleges across the United States are a serious concern for everyone.
