Type I and type II errors

uncertainty [4, 5]. Because of uncertainty in measurement, there is always the risk of mistaken decisions about that whether it is consistent with the specified requirements for certain characteristics or not. Such mistaken decisions are of two types [6]: I. A quantity accepted as conforming might actually be…

I. PURPOSE The purpose of this lab was to observe the physical properties of different samples of matter and to use your observations and knowledge of chemistry to classify each sample as an element, a compound or a mixture. II. MATERIALS 10 beakers containing different samples of matter III. PROCEDURE First off, put on a laboratory apron. Then, take a few minutes at each lab station and record three physical property observations of each sample of matter. Record the three physical property…

Reporting of errors relies on voluntary reporting. Traditionally, the nursing profession has operated based on a culture of fear and blame that focuses on individual culpability rather than looking at problems from a system-wide perspective. There can also be some ambiguity with regards to what actually constitutes a medication error (e.g., is late delivery of a dose a medication error?) and there is often reluctance to report errors that do not result in patient harm. Often…

of the boys were born in Baltimore, and in the projects. As they develop into two young men during the reading of the book, they seem to get a first preview towards the struggles of life. They could be told apart from one another, because Wes I, and Wes II, are completely different persons, but share with themselves similarities. The boys each endure a critical moments and phase in their lifetime, in which they get a second opportunity in life, to change for their own wellbeing. They are without…

They are records of measurement, counts or observations. Examples of data are body weights of calves [3]. There are four types of data: nominal, ordinal, interval and ratio. Qualitative variables are measured with nominal and ordinal, while quantitative variables are measured with interval and ratio scale of measurement [5].The type of data is an important factor in determining which computations are suitable. Descriptive statistics Data collected and organized by the experimenters…

I.1- INTRODUCTION: Conformational analysis is the study of the energy change, a molecule undergoes, as it rotates about one or more single bonds. The conformations of a molecule are those arrangements in space of the atoms which are not superimposeable upon each other. The basic idea behind conformational analysis is that molecules will have certain physical and chemical and thermodynamic properties that are dependent on the preferred conformations. in the modern chemistry, where it can…

In Part I of this series I discussed some of the facts and myths about Alzheimer's and dementia. In Part II I presented five…

Ceccoli’s Pill Politics: Drugs and the FDA, this formal change in the mission symbolizes the transformation of the agency’s priority to avoid Type II errors with the same diligence as avoiding Type I errors. While Type II errors can go completely unnoticed by the public, the environment in which the FDA was working during this time was hyperaware of such errors, following the AIDS epidemic. Prior to the AIDS epidemic and social activism surrounding it, it was nearly universally agree upon that…

one point to another point in FSO communication an error may occur. This means a signal corresponding to 0 may change to 1 or vice –versa due to presence of noise. Figure 5. shows the basic coding block diagram of FSO communication system. Fig.5. FSO communication system with coding It is possible to improve the reliability of FSO communications system and achieve predetermined Bit Error rate (BER) by utilizing coding schemes. Forward error correcting codes (FEC) are leading an important…

One day after practice I came home hot-headed. The entire way home I sat in the car percolating about a comment my coach made toward me. As soon as I opened the door, I dropped my bags and marched straight up to my mom, looking for some comfort, and told her that my volleyball coach just called me lazy. I told her the story just how it happened. It was towards the middle of practice and the team was working on blocking. This involved swift lateral movement from the middle of the net to the…
