Reliability of Statistics Today, most of us live in a world surrounded by data. Everything that we do calculates findings to supply data for statistical findings to show that it is either wrong or right. Statistics is not a new process in our lives; it has been around for close to 400 years of the history I was able to find discussing statistics or probability. The oldest date found was identified by Stigler (1999 p. 207) were he explained that in 1628 a William Harvey released a study of the motion of blood and the heart. The study, which consisted of statistical facts, proved that blood passes through the body by the pulsation of the heart. To us in today’s world that does not sound like a great discovery. Ordinarily, to the world that did not know the method of how the blood flowed through the body, it was a great achievement. Without recognizing the research as being statistical, we can go back even further to find that one of the items perhaps found in your garden today is, in fact, one of the oldest known timekeepers in the world, the sundial. â€Å"The sundial existed in a very primitive form in Egypt from at least the 15th century B.C.† (Bigliazzi, Spaans, Dunaud, Juran, 1995). Discovery of one of the initial specimens of a sundial was in Greece in which dated back to the third century B.C. In Greece, they studied the mathematics of the sundial, which in turn led to improving the accuracy of the timekeeper. In order to establish and improve the accuracyShow MoreRelatedReliability Of Statistics : Statistics Essay2661 Words   |  11 PagesReliability of Statistics Today most of us live in a world surrounded by data.

However, the reliability of data is mostly confined to a smaller volumes. Statistics, when dealing with larger volumes of data exhibit inaccurate results. There are many factors which affect the end results. This might be due to the improper sampling, improper handling ofRead MoreStatistical Research in Psychology999 Words   |  4 PagesMany students, including myself, are unaware how important statistics can be to the research process in Psychology.

The motivation for contracting Romax instead of performing an estimate ourselves is that Romax can do a better job than AWST due to a larger database of failure modes and deeper expertise. Due to this reason, AWST does not have a model that could have ingested the data even if it was available that is an additional barrier for in-house cost model. ThisRead MoreEvaluate the usefulness of quantitative methods in sociological research990 Words   |  4 Pagesquestionnaires or interviews with closed-ended questions, statistics, the use of secondary data and experiments (with a control group and an experimental group).

(2006) used the Ottawa GRS in a pilot study at the University of Ottawa to evaluate whether high-fidelity simulation can be used to measure Crisis Resource Management (CRM) performance and to ascertain the construct validity of the Ottawa GRS. Construct validity of the Ottawa GRS was determined by evaluating the content validity, response process, internal structure and relationship to other variables while reliability was measuredRead MoreIntroduction: There are many factors that contribute to students’ academic success, such as low800 Words   |  4 Pageslevel of work drive, being emotionally stable, and a low level of negative life stress.
