Deandra Statistics in Psychology and its function cannot be taken lightly. The importance ofthe development of psychology would not have been realized if statistics did not play such a crucial role. Important components such as inferential statistics and interactions are dynamic in the study of associations, and affiliations that are essential in psychology.Statistic is the exact phenomenon of nature and it helps in providing a better understanding.

...Descriptive and Inferential Statistics PSY/315 Statistical Reasoning in Psychology September 21, 2013 Dr. Nancy Walker Descriptive and Inferential Statistics Statistics is “a branch of mathematics that focuses on the organization, analysis, and interpretation of a group of numbers” (Aron, Aron, & Coups, 2009, p. 2). However, just the mention of statistics makes people nervous, although when properly understood, many of the questions statistics tries to answer are very provocative and challenging. Statistics are a collection of information and, data that helps test the theory something is happening or will happen again. The functions of statistics are there to help researchers have a better understanding of a phenomenon. Statistics can be used when looking for the truth, if you have ever had a hunch about something, was it confirmed? Yes the hunch was confirmed. Statistics help researchers with data by using math and working with a group of numbers. Statistics studies variables, characteristics that have different values, values, possible number that a score can have, and score one person value of a variable (Aron, Aron, & Coups, 2009). Descriptive and inferential statistics are to evaluate results and enable one to make a conclusion. Descriptive statistics are a way to describe data (Laird Statistics, 2013), as well as to “summarize and describe a group of numbers from a research study,” whereas, inferential statistics are used to “draw conclusions and...

...Using a spot the difference puzzle to find out whether being a lark or an owl affects your alertness in the morning or the evening. Results were then tested on significance using the Wilcoxon T test to decide whether the results found were reliable, or just down to chance. In theory, a lark should be more alert in the morning than in the evening compared to an owl who would be more alert in the evening. To test thins the participants were given two spot the difference puzzles and had to complete one in the morning and one in the evening. This in using the repeated measures method. This was tested on 49 participants who completed an MEQ (morning evening questionnaire) particapnats were tested in their homes at set times and given 1 minute to complete the spot the difference puzzles. Results were then tested on significance using the Wilcoxon T test to decide whether the results found were reliable, or just down to chance. Introduction The aim of the investigation was to find out the answer to the question ‘are people more alert at their preferred time of day?’ To test this, the procedures were based on the theory that A lark should be more alert in the morning and so should be able to score higher in the morning than the evening and an owl should be more alert in the evening than the morning therefore scoring higher than the larks in the evening. This hypothesis is a One-tailed Hypothesis because it is directional, these are the 4 possible hypothesis that can be tested...

...Business Research RES/351 Business Research With looking to open a new Tattoo shop in the Plymouth area, we need to look at many things before we can open the doors. We must consider our research problem and purpose, our research design, sampling methods, the analysis of our research, and any ethical considerations we need to look at. With this information, we want to see if Plymouth is the right place for us to open our Tattoo shop and it being a profitable location. There are many questions to ask with opening a new tattoo shop, from what is a good location to what our profit margins would be. One-research question to ask is; do we have clientele in the same location as where we want to open our business? This is an important question because even though people are willing to travel to get a quality and personal tattoo, local clientele still account for profits. A second question to ask is; will we gain profit at this location? As in any business, we are in it to make profit, not debt. A third question to ask is; is there competition in the area? We as new business owners need to know if there are any other tattoo parlors in the area where we would like to open up, and if so, what kind of service and body artwork are they offering? Are they the same type of body art we are going to offer our clientele? A fourth question to ask is; what will it cost to open the doors for the first year? The last question is the most important question we need to ask ourselves...

...“excuse” that Paret was purposely demonstrating a skill had a smaller impact on Paret’s publicity. Through detail, the reader is able to sympathize the gruesome fight and eventual death of Paret. Mailer mentions that Griffith hit Paret “eighteen right hands in a row” in about “three or four seconds”. These details create imagery and allow the audience to imagine Paret’s situation. When Paret died, it seemed to last forever. The details of how Paret slowly died while Griffith was still punching him greatly affects the audience in that Paret was technically still fighting when he passed. Mailer also uses syntax to strongly tough the audience. The statement “Paret died on his feet” was different from his usual style of long, descriptive sentences. This makes it stand out more and is more compelling. His tone throughout the passage is prideful, mixed with a touch of disgust. Mailer simply states that Paret’s...

...Hannah Higginson June 23, 2013 ENG 120 Sec B03 Summer 2013 Literary Analysis Essay 1 A Strong Bond The theme in “Barn Burning” by William Faulkner revolved around the strong bond of a family. The main character has to make a decision between what is right and wrong. This drives a wedge between him and his family. The rest of the family believes that blood is thicker than water and that you should stick with your own kin. In the story the strong bond of a family causes conflicts within the main character. Faulkner starts “Barn Burning” with a view of a small courthouse. Sarty sits outside as his father, Abner, argues with the Justice of the Peace. This shows just how little respect Abner has for the law. Abner is being accused of setting someone’s barn on fire. The Justice rules that Abner should pack his belongings and leave the country before dark. Abner and his sons then head out to the wagon where the rest of his family awaits. They ride for a while before camping out in some trees. The next day they arrive at the house and begin unpacking. Then Abner leaves and sets route to the De Spain’s house. Upon arrival he barges through the door and calmly wipes his feet over the expensive white carpet. He has no respect for others or their belongings. A couple hours later a man arrives with the rug and tells Abner to clean it. He does not only clean the rug, but he also sets it on fire to prove that he is above the law. After getting in trouble with the Justice of Peace...

...Exercise E – Strategic Alliances We can see a combined chart of institutional distance and ownership commitment both for developed and emerging markets. The relationship is the following: If a firm from an emerging market decides to enter South Africa the higher the ownership commitment is the higher the institutional distances get. Institutional distance describes the extent of the similarity or dissimilarity between two countries (focusing on informal-formal, cognitive-normative and regulative) it is also an important factor as institutions dictate the rules of the game (North 1990). High institutional distance picture a challenging economic environment for new entry firms who have to face the liability of foreignness. This distance mean increased transaction costs, higher information costs and uncertainty. Which is especially important as South Africa is ranking only 50 on property right indexes. The other chart describes the relation between ownership commitment and the nature of knowledge, which shows that to actually gain the Location and Ownership specific advantages ( as Sumatra Inc. is looking for a locally embedded partner, Dunning – OLI paradigm) higher degree ownership commitment is required. This tacit knowledge can be tapped by equity investment or co-op. Tacit knowledge is embedded in the company’s socially complex organizational routines and employee skills, expertise. Making it hard to codify. The most effective way of learning complex know-how’s is to...

...Statistics in Psychology Team B April 5, 2014 PSY/315 Nancy Walker Many people find the topic of statistics to be very difficult and a world of confusion. If asked, most would simplify statistics to being a breakdown of information using those colorful charts and graphs. This paper will give a brief introduction into the world of statistics by examining the differences between descriptive and inferential statistics, as well as, introduce some key terms that are frequently used. It will also describe the functions of statistics and describe how they are applied in the field of psychology. Having a better understanding of the various statistical functions and definitions, we will have a better opportunity at providing examples and prove that statistics is more than just colorful charts and graphs. Statistics is where a large amount of data is put together in a format that allows the viewer to understand it better. Whenever choosing an experiment that results in statistics, one would start with a hypothesis, or idea. This gives the entire process a purpose. The function of statistics appears for various reasons. When there is a large amount of data, it organizes it so that a viewer and/or a presenter can comprehend or present it easier. A way that it is organized is through charts and graphs, which shows the clarity. Another function is to show comparisons between two or more clumps of data. Statistics helps in forecasting trends and tendencies. Statistical techniques...

...Leonardo Castillo Enc 1101 M/W 5:00 pm 10/1/2012 Word count: 709 Descriptive Essay Rough draft It’s approximately four o’ clock in morning and I’m in the locker room changing my clothes. My colorless hands are chilly, my feet are weary and my body feels like is going to give up and collapse after working eight hours in a refrigerated warehouse. Even though my body just wants to give way, I manage to drag my feet all the way to my vehicle, and start rushing home which is the only thing I want to do after a long night of work. The best part of driving home at this hour of the day is that I have an open road almost all to myself. The streets are nearly empty, the drive nice and smooth and the best part is that there are no police so you can run through these streets like there’s no tomorrow. Also there are no rays of sunshine burning my eyes like in the day, the weather is nice and cool that I don’t even need to turn on my a/c which has been throwing nothing but burning air. As I get closer to home I could only think about going straight to comfy bed; however, it is not going to happen because this is the only free time during the day that I have time to study. As I am getting to the door my eyes feel unfocused and my eyelids are feeling heavy. Now that I made it to the white tarnished door, I am shuffling through my key chain to find the correct key. The darkness of the night makes it difficult to find the right one; thus, I lift my arm up toward the sky to see if...

...“The day was ending in a serenity of still and exquisite brilliance (S). The water shone pacifically; the sky, without a speck, was a benign immensity of unstained light; the very mist on the Essex marshes was like a gauzy and radiant fabric (m&s), hung from the wooded rises inland, and draping the low shores in diaphanous folds. Only the gloom to the west, brooding over the upper reaches, became more somber every minute, as if angered by the approach of the sun. (H)” S- syntax M&S- Metaphor and simile H- Hyperbole Conrad used syntax, metaphor and simile and hyperbole in this passage. He used syntax to stress how the day was ending and make it more detailed. With the use of a metaphor and simile he compared the Essex marshes to a “gauzy and radiant fabric” giving the reader an idea of what the marsh may look like. With this literary device Conrad is trying to draw a picture for the reader. Lastly, Conrad uses a hyperbole to really exaggerate the gloom over the west. With the use of “somber” and “angered” he is exaggerating the gloom giving the reader an idea of to what extent the gloom is. "The idleness of a passenger, my isolation amongst all these men with whom I had no point of contact, the oily and languid sea, the uniform somberness (D) of the coast, seemed to keep me away from the truth of things, within the toil of a mournful and senseless delusion. The voice (S) of the surf heard now and then was a positive pleasure, like the speech of a brother (A). It...
