Introduction for expected value of sample information tutor:
Expected value is the main thought in probability, in an intellect more general than probability itself. The expected value of a real-valued selection variable offers a compute of the center of the distribution of the variable. More considerably, by taking the expected value of various functions of a common random variable, we can calculate a lot of interesting features of its distribution, including spread and correlation. Tutor is a personality working in the education of others, either separately or in group.
Formula for expected value of sample information tutor:
The following formula for expected value of sample information tutor which is used to compute expected value for discrete random variable shows given below.
Expected value E(x) = sum (xi. P(xi))
x = discrete random variable
P(x) = probability distribution

In 1969, Donald H. Meichenbaum, Kenneth S. Bowers, and Robert R. Ross replicated a study of the remarkable Expectancy Effect study from Robert Rosenthal. Rosenthal had conducted numerous studies with a hypothesis of confirming that one person’s expectations affect another’s behavior, which is also referred as the self-fulfilling prophecy. This hypothesis was also used by Meichenbaum, Bowers, and Ross in their experiment. Under the Behavioral Analysis of Teacher Expectancy Effect study, 14 adolescent female offenders were examined over a period of a month. Six were chosen to be identified as “late bloomers” to their four teachers. During the study, the late bloomers improved significantly higher on objective exams, but not in subjective. However, their behavior in class improved as well. The observations of the teacher-pupil interactions during the 2 week expectancy period revealed that the instructions affected significantly and increased on the positive interactions among the late bloomers. The study conducted by Meichenbaum, Bowers, and Ross has several differences than Rosenthal’s study. Firstly, they created a different study with only 14 female adolescent offenders that were institutionalized in a training school. Secondly, the training school had limited time of two weeks under expectancy effect. Therefore they were graded based on objective test, subjective tests, and measures in their behavior instead of IQ change. Thirdly, the teachers had known the students prior to the study and had created their own expectancies of the girls’ intellectual capabilities. The study may have several differences, but the general aspects of examining the behavior of teacher expectancy and the effect of the academic performance on the adolesc...

When a teacher from Tryhard high school decides to voice her/he’s distaste about the success of the students from the previous year in mathematics, a few students decide to take matters into their own hand. Using the scores of the previous years they started to analyses the documents and see if the teacher was wrong.
This reinforces their academic commitment and motivates the students to complete set tasks, where they are rewarded for their behaviour. There are also fixed-interval schedules, where Miss Johnson is rewarded with a salary for teaching the students. This encourages her to strive to engage her students and not give up on them, as she desires the reward of her pay cheque. A variable-interval schedule is also explored, where she is rewarded for her dedication and commitment to engage the students, as they eventually perceive her as their “light”. In addition, there are variable-interval schedules, where Miss Johnson is rewarded with good behaviour form her students after an unspecified amount of
In the article “I Just Wanna Be Average” Mike Rose teaches us we go through various obstacles in life. OFten we need someone who sees our potential in order to succed as the person we’ve always wanted to become. For example, Rose’s Sophmore Biology teacher noticed his good grades on tests and decided to look into it. There he realized Rose was in the wrong program the whole time. “He checked the school records and discovered the error. He reccommened that I beigin Junior year in the college prep program.” (Rose 4) Another example would be during Senior year when Rose’s English teacher Mr. MacFarland worked hard at this job as it showed in the way he taught students inspiring them with intellegence. “He analyzed poems with us… making a potentially difficult book accessible with his own explinations.” (Rose 5)
Introduction to the basic concepts of probability and statistics with discussion of applications to computer science.
The author argues that certain decision leads to vast amount of untapped human potential and limits success to few who are selected unjustly. This example supports “Mathews Effect”. The Gladwell’s example of Bill Gates proves the “10,000 Hour Rule”, He explained that the timing and opportunity played a huge role to become an expert at computer programming. Bill Gates had access to computers decades before computers became mainstream. Such a timing helped him capture the opportunity to master the tool of trade and put him in the perfect position to start Microsoft. The Gladwell’s example of experiment by Lewis Terman, He argues about that a person’s IQ have a limited control over success. He claims that there is a minimal difference in the levels of success attained by those with IQs between 125 and 170. The author adds that IQ cannot efficiently measure person’s creativity. A person who has a high IQ does not mean that it has a high chance of winning a Nobel Prize because other kind of intelligence matter too. With the help of these facts, Gladwell proves that the relationship between IQ and success is
P is the subjective probability of the being caught and convicted; U(_) is the individuals utility function, which depend on Y and F; Y is the benefits from committing crime; F is the cost from committing crime if caught, such as punishment.
The book is divided into five parts according to different fields. In first part, five papers are focused on applications of statistical methods in public policy and social science. Hypothesis testing was used to determine the guilty of a suspect in the courtroom. Probability distribution and sampling were used to analyze candidate preference for an election polling. Besides, people applied modeling method to figure out that Utah could get an extra seat in U.S. House of Representatives unless North Carolina lost one seat. In order to evaluate school choice programs, getting quantitative evidence from randomized experiments was easier than from observational studies, though evaluators would deal with missing data and noncompliance. To understand health care spending, a survey was ...

...college student, etc.) has to learn something new from another person who is already experienced in the area that the learner is trying to master.
In the world today, individuals continuously learn new things and acquire skills and knowledge all through their lives (Billett 2010; Alheit and Dausien, 2002). Most of these skills and knowledge acquired by individuals are mostly useful for their career growth and also for the entire society, while some are trivial.
Professor Betar has high expectations from all his students in class that gave us a push to do better in high school. Betar believes that if he has high expectations from us we would tend to do better. Unlike if a teacher has low expectations of his student; student would lose their self-confi...
The Collier Encyclopedia’s definition for probability is the concern for events that are not certain and the reasonableness of one expectation over another. These expectations are usually based on some facts about past events or what is known as statistics. Collier describes statistics to be the science of the classification and manipulation of data in order to draw inferences. Inferences here can be read to mean expectations, leading to the conclusion that the two go hand in hand in accomplishing what mankind has tried to accomplish since the beginning of time – predicting the future. It is the notion of science that this is the most accurate way to predict events yet to occur and this has lead to it being the most widely accepted “fortune telling'; tool in the world today.
In the world today, information is an important aspect in almost every part of our life. From what time the movie we want to see begins to whether we should buy stock in Dell or IBM, we depend on accurate information. Is this kind of information a commodity? The dictionary defines a commodity as something valuable or useful (Webster 1993). Presently, information is a commodity because people are willing to pay high prices for information in order to make better decisions. In this paper, I will give many examples of how information acts as a commodity. I will also show how information acts as a commodity in other areas than just technology and business.
