The Lady Tasting Tea
The different tastes between pouring milk into tea or tea into milk raised R.A. Fisher’s interest to design an experiment for testing the lady. Dr. David Salsburg used this famous anecdote as the book title, and elaborated the development of modern statistics by several stories. Each chapter contains one outstanding statistician and his/her contributions. Impressively, the whole book was linked by R.A. Fisher, K. Pearson, E. Pearson and J. Neyman, these exclusively distinguished statistician, which indicates their fame and masterpiece has great impact on not only statistics but also academia of science, even our daily life.
Probability defined by Aristotle, “improbable things will happen”. Later on, the probability and

Savage and Bruno de Finetti, the confidence interval was justified by the Bayesian theory of personal probability. Bayes’s theorem is separated from Pearson’s probability, and the idea of inverse probability is sort of taboo in statistics academia. That is the reason why confidence interval was disregarded by the chair. The personal probability and Bayesian Hierarchical model are two approaches more and more prevalent than Pearson’s age.
Kolmogorov furthered the probability and statistics into real life and made it more suitable than “pure” mathematics. He inaugurated the axiomization of probability theory and setup the abstract space of elementary things as “events”. This practical axiom made forward movement of probability measurement in reality.
After reading this book, I am touched by the underlying philosophy of statistics. Various theories and models are introduced in this book. During the progress of the development, controversies and confits among these theories are largely attributable to diversity of ideology and doctrine from their establishers. In future, the statistics might evolve into a new era and the vogue methods, like p-value or confidence interval, might be discarded. I am looking forward to witness how statistics make our lives
Inferential statistics establish the methods for the analyses used for conclusions drawing conclusions beyond the immediate data alone concerning an experiment or study for a population built on general conditions or data collected from a sample (Jackson, 2012; Trochim & Donnelly, 2008). With inferential statistics, you are trying to reach conclusions that extend beyond the immediate data alone. For instance, we use inferential statistics to try to infer from the sample data what the population might think. A requisite for developing inferential statistics supports general linear models for sampling distribution of the outcome statistic; researchers use the related inferential statistics to determine confidence (Hopkins, Marshall, Batterham, & Hanin, 2009).
The final chapter of this book encourages people to be critical when taking in statistics. Someone taking a critical approach to statistics tries assessing statistics by asking questions and researching the origins of a statistic when that information is not provided. The book ends by encouraging readers to know the limitations of statistics and understand how statistics are
For people who are not statisticians, they may wonder what statisticians do, and how statistics could be applied in daily life. Statistics: A Guide to the Unknown is a supplementary reading materials designed for general readers even if he or she did not learn enough knowledge of statistics, mathematics and probability. Besides, it could give statisticians a general understanding of the important role of statistics in society. This book also analyzes how statistics assists people to gain useful information from massive data sets. In order to form a more respected book, the editors invite many distinguished researchers in statistics as authors. The book consists of twenty-five essays from different fields, including public policy and social science, science and technology, biology and medicine, business and industry, and hobbies and recreation. Each essay provides readers a description of how statistical methods are applied to solve issues in that field.
Jeanne Wakatuski is a young girl who had to endure a rough childhood. She thought herself American, with a Japanese descent. However, with WWII and the internment camps, Jeanne struggled to in understanding who she really was. It started with Manzanar, at first she knew herself as a Japanese American. Living in Manzanar gave her a new perspective, “It (Manzanar) gradually filled me with shame for being a person, guilty of something enormous enough to deserve that kind of treatment” (Houston and Houston 161). Jeanne faced the problem of being someone who was not wanted or liked in the American society. A good section that shows the discrimination at the time was when Jeanne tried to join the Girl Scouts, which is on page 144. She was turned

The best loose leaf tea offers various potential wellbeing profits. The primary importance of drinking loose leaf teas is that they are of higher quality. The clarification for this is basic. On buying loose leaf, whether it is loose leaf green tea or natural loose leaf tea, you get entire leaves, which hold their vital oils. In any case, what happens in the other hand is that the leaves utilized within sacks are frequently tea clean and leaf parts. The tea dust is gathered after the leaves are picked and transformed. These sections when put into sacks, lose their fundamental oils, which commonly exist in entire clears out. On the off chance that the tea in the sacks, if at all holds a percentage of the oils, then they are of low quality.

This chapter taught me the importance of understanding statistical data and how to evaluate it with common sense. Almost everyday we are subjected to statistical data in newspapers and on TV. My usual reaction was to accept those statistics as being valid. Which I think is a fair assessment for most people. However, reading this chapter opens my eyes to the fact that statistical data can be very misleading. It shows how data can be skewed to support a certain group’s agenda. Although most statistical data presented may not seem to affect us personally in our daily lives, it can however have an impact. For example, statistics can influence the way people vote on certain issues.

Multivariate statistics concerns understanding the different aims and background of each of the different forms of multivariate analysis, and how they relate to each other. The practical application of multivariate statistics to a particular problem may involve several types of univariate and multivariate analyses in order to understand the relationships between variables and their relevance to the actual problem being studied.
In the health care industry, gathering information in order to find the best diagnosis route or even determine patient satisfaction is necessary. This is complete by conducting a survey and collecting data. When the information is complete, we then have statistical information used to make administrative decision within the healthcare field. The collection of meaningful statistics is an important function of any hospital or clinic.
I was very glad to see those comments, because it was my ultimate aim that let it be known that about the Japanese ceremony.
Imagine millions of Afghani refugees, emaciated families, and thousands of uneducated children all desperate for help. In the war that America has waged against terror, it has left in its wake millions of peaceful, starving, and struggling civilians. Both, Three Cups of Tea by Greg Mortenson and David Oliver Relin and The Kite Runner by Khaled Hosseini display the two different stories about the reality of living in the midst of war. Using contrasting brushstrokes, these two stories paint a vivid picture of the fragile and tumultuous society that millions of peaceful Afghani and Pakistani civilians claim as their own.
Whether or not people notice the importance of statistics, people is using them in their everyday life. Statistics have been more and more important for different cohorts of people from a farmer to an academician and a politician. For example, Cambodian famers produce an average of three tons or rice per hectare, about eighty per cent of Cambodian population is a farmer, at least two million people support party A, and so on. According to the University of Melbourne, statistics are about to make conclusive estimates about the present or to predict the future (The University of Melbourne, 2009). Because of their significance, statistics are used for different purposes. Statistics are not always trustable, yet they depend on their reliable factors such as sample, data collection methods and sources of data. This essay will discuss how people can use statistics to present facts or to delude others. Then, it will discuss some of the criteria for a reliable statistic interpretation.
This paper discusses different types of sampling techniques used in quantitative research. It begins by looking at probability sampling (also known as random sampling) before discussing non-probability sampling (non-random sampling). The discussion ends by looking considerations that should be made before selecting a sampling technique before concluding. Because quantitative researchers prefer probability sampling and only use non-probability on rare occasions the e...
