Exploratory Data Analysis Essay Exploratory Data Analysis Using the dataset Chamorro-Premuzic. sav, exploratory statistical analysis was carried out on the variables in the dataset. Scatter plots were formulated t give a clear visual view of the data for Extroversion and Agreeableness. Descriptive statistics were also formulated for the variables. 2. Decision about the missing data 3. Correlation A correlation analysis was carried out on the data for Extroversion and Agreeableness. 4. Regression.  A regression analysis was carried out on the data for Extroversion and Agreeableness to examines whether or not one can predict if a student wants a lecturer to be extroverted using the student’s extroversion score. The analysis was two-tailed since the answer sought to determine if the student wants a lecturer to be extroverted or not, and hence any deviation from the answer either positively or negatively would lead to rejection of the null hypothesis. (Triola, 2009) 5. Multiple Regression A multiple regression analysis was carried out to determine whether age, gender, and student’s extroversion can predict if a student wants the lecturer to be extroverted. (Lewicki, 2007) Part B. Applying Analytical Strategies to an Area of Research Interest 1. Research area of interest. The research was aimed at examining the relationship between extroversion and Agreeableness by lecturer and students on what to consider for extroversion. a. Pearson Correlation A parametric correlation analysis that seeks to identify any relationship between two variables. b. Spearman’s Correlation This is a correlation analysis that is non-parametric and aimed at identifying any relationship between two variables. c. Partial Correlation vs. Semi-Partial Correlation Partial correlation analysis is an analysis that seeks to identify the degree of a relationship between two variables when controlling factors has been introduced in the analysis. Semi-partial correlation analysis is an analysis that seeks to control the effect of a third variable in multiple regression and then finding the relationship between the remaining two variables. The method however retains the variation caused by the third variable that is removed from the equation. d. Simple Regression e. Multiple Regression f. Logistic Regression Logistic regression is a regression that seeks to identify the probability of occurrence of an event in a logit function. The regression model is used for binomial regression models. References Hill, T. and Lewicki, P. (2007). Stataistics Methods and Applications. London: Croom Helm. Triola F. (2009).

A Need For Education :: essays research papers

The Once And Future King by T.H White is a four part book of magic, love, death, war and medieval tales. The book tells the tale of how the Wart (Arthur) becomes king and how he goes about life. The need for education is very important; the lessons Arthur learns and his application of them later in life demonstrates this importance.   Ã‚  Ã‚  Ã‚  Ã‚  The lessons Arthur learns as a child is taught to him by various animals. On the signs over each ant tunnel was a notice which read,† Everything Not Forbidden Is Compulsory† (122). In the life of a worker ant there is no free thought allowed. The worker ants also have no free will; they do only what they are told to do and nothing else. Another good example is the view of Lyo-lyok the goose; â€Å"There are no boundaries among the geese† (170). Lessons learned from the geese are those that teach leaders take charge when a leader is needed. The geese also teach Arthur why war is unnecessary. In those lessons Arthur learns that Communism is oppression, is war, and Lyo-lyok teaches that war is not the only thing one should depend on.   Ã‚  Ã‚  Ã‚  Ã‚  Later in Arthur’s life, he uses his education to form ideas of using might for right. For example, Arthur rhetorically inquires, â€Å"Why can’t you harness might so that it works for right† (248)? Asserting his idea Arthur decides to fight the battle at Bedegraine in hopes of stopping people from thinking of war as he once did. With that idea in mind Arthur wishes to use might to show people what is right. Arthur then decides to enforce his idea of might for right by creating a league of knights (The Knights Of The Round Table); this idea leads to a genius proposal in when he states, â€Å"Then we can have a circular table† (265). Arthur’s round table idea prevents jealousy and competition among the knights.

The Vampire Diaries: The Struggle Chapter One

â€Å"Damon!† Icy wind whipped Elena's hair around her face, tearing at her light sweater. Oak leaves swirled among the rows of granite headstones, and the trees lashed their branches together in frenzy. Elena's hands were cold, her lips and cheeks were numb, but she stood facing the screaming wind directly, shouting into it. â€Å"Damon!† This weather was a show of his Power, meant to frighten her away. It wouldn't work. The thought of that same Power being turned against Stefan woke a hot fury inside her that burned against the wind. If Damon had done anything to Stefan, if Damon had hurt him†¦ â€Å"Damn you, answer me!† she shouted at the oak trees that bordered the graveyard. A dead oak leaf like a withered brown hand skittered up to her foot, but there was no answer. Above, She turned – and gasped. He was just behind her, so close that her clothes brushed his as she turned. At that distance, she should have sensed another human being standing there, should have felt his body warmth or heard him. But Damon, of course, wasn't human. She reeled back a couple of steps before she could stop herself. Every instinct that had lain quiet while she shouted into the violence of the wind was now begging her to run. She clenched her fists. â€Å"Where's Stefan?† A line appeared between Damon's dark eyebrows. â€Å"Stefan who?† Elena stepped forward and slapped him. She had no thought of doing it before she did it, and afterward she could scarcely believe what she had done. But it was a good hard slap, with the full force of her body behind it, and it snapped Damon's head to one side. Her hand stung. She stood, trying to calm her breath, and watched him. He was dressed as she had first seen him, in black. Soft black boots, black jeans, black sweater, and leather jacket. And he looked like Stefan. She didn't know how she could have missed that before. He had the same dark hair, the same pale skin, the same disturbing good looks. But his hair was straight, not wavy, and his eyes were black as midnight, and his mouth was cruel. He turned his head slowly back to look at her, and she saw blood rising in the cheek she'd slapped. â€Å"Don't lie to me,† she said, her voice shaking. â€Å"I know who you are. I knowwhat you are. You killed Mr. Tanner last night. And now Stefan's disappeared.† â€Å"Has he?† â€Å"You know he has!† Damon smiled and then turned it off instantly. â€Å"I'm warning you; if you've hurt him – â€Å" â€Å"Then, what?† he said. â€Å"What will you do, Elena? Whatcan you do, against me?† Elena fell silent. For the first time, she realized that the wind had died away. The day had gone deadly quiet around them, as if they stood motionless at the center of some great circle of power. It seemed as if everything, the leaden sky, the oaks and purple beeches, the ground itself, was connected to him, as if he drew Power from all of it. He stood with his head tilted back slightly, his eyes fathomless and full of strange lights. â€Å"I don't know,† she whispered, â€Å"but I'll find something. Believe me.† â€Å"I do believe you,† he said, relaxing, looking around the graveyard. Then he turned back and held out a hand to her. â€Å"You're too good for my brother,† he said casually. Elena thought of slapping the hand away, but she didn't want to touch him again. â€Å"Tell me where he is.† â€Å"Later, possibly – for a price.† He withdrew his hand, just as Elena realized that on it he wore a ring like Stefan's: silver and lapis lazuli. Remember that, she thought fiercely. It's important. â€Å"My brother,† he went on, â€Å"is a fool. He thinks that because you look like Katherine you're weak and easily led like her. But he's wrong. I could feel your anger from the other side of town. I can feel it now, a white light like the desert sun. You have strength, Elena, even as you are. But you could be so much stronger†¦Ã¢â‚¬  She stared at him, not understanding, not liking the change of subject. â€Å"I don't know what you're talking about. And what has it got to do with Stefan?† â€Å"I'm talking about Power, Elena.† Suddenly, he stepped close to her, his eyes fixed on hers, his voice soft and urgent. â€Å"You've tried everything else, and nothing has satisfied you. You're the girl who has everything, but there's always been something just out of your reach, something you need desperately and can't have. That's what I'm offering you. Power. Eternal life. And feelings you've never felt before.† Shedid understand then, and bile rose in her throat. She choked on horror and repudiation. â€Å"No.† â€Å"Why not?† he whispered. â€Å"Why not try it, Elena? Be honest. Isn't there a part of you that wants to?† His dark eyes were full of a heat and intensity that held her transfixed, unable to look away. â€Å"I can waken things inside you that have been sleeping all your life. You're strong enough to live in the dark, to glory in it. You can become a queen of the shadows. Why not take that Power, Elena? Let me help you take it.† â€Å"No,† she said, wrenching her eyes away from his. She wouldn't look at him, wouldn't let him do this to her. She wouldn't let him make her forget†¦ make her forget†¦ â€Å"It's the ultimate secret, Elena,† he said. His voice was as caressing as the fingertips that touched her throat. â€Å"You'll be happy as never before.† There was something terribly important she must remember. He was using Power to make her forget it, but she wouldn't let him make her forget†¦ â€Å"And we'll be together, you and I.† The cool fingertips stroked the side of her neck, slipping under the collar of her sweater. â€Å"Just the two of us, forever.† There was a sudden twinge of pain as his fingers brushed two tiny wounds in the flesh of her neck, and her mind cleared. Make her forget†¦Stefan. That was what he wanted to drive out of her mind. The memory of Stefan, of his green eyes and his smile that always had sadness lurking behind it. But nothing could force Stefan out of her thoughts now, â€Å"I've already found what I want,† she said brutally. â€Å"And who I want to be with forever.† Blackness welled up in his eyes, a cold rage that swept through the air between them. Looking into those eyes, Elena thought of a cobra about to strike. â€Å"Don't you be as stupid as my brother is,† he said. â€Å"Or I might have to treat you the same way.† She was frightened now. She couldn't help it, not with cold pouring into her, chilling her bones. The wind was picking up again, the branches tossing. â€Å"Tell me where he is, Damon.† â€Å"At this moment? I don't know. Can't you stop thinking about him for an instant?† â€Å"No!† She shuddered, hair lashing about her face again. â€Å"And that's your final answer, today? Be very sure you want to play this game with me, Elena. The consequences are nothing to laugh about.† â€Å"Iam sure.† She had to stop him before he got to her again. â€Å"And you can't intimidate me, Damon, or haven't you noticed? The moment Stefan told me what you were, what you'd done, you lost any power you might have had over me. Ihate you. You disgust me. And there's nothing you can do to me, not any more.† His face altered, the sensuousness twisting and freezing, becoming cruel and bitterly hard. He laughed, but this laugh went on and on. â€Å"Nothing?† he said. â€Å"I can doanything to you, and to the ones you love. You have no idea, Elena, of what I can do. But you'll learn.† He stepped back, and the wind cut through Elena like a knife. Her vision seemed to be blurring; it was as if flecks of brightness filled the air in front of her eyes. â€Å"Winter is coming, Elena,† he said, and his voice was clear and chilling even over the howl of the wind. â€Å"An unforgiving season. Before it comes, you'll have learned what I can and can't do. Before winter is here, you'll have joined me. You'll be mine.† The swirling whiteness was blinding her, and she could no longer see the dark bulk of his figure. Now even his voice was fading. She hugged herself with her arms, head bent down, her whole body shaking. She whispered, â€Å"Stefan – â€Å" â€Å"Oh, and one more thing,† Damon's voice came back. â€Å"You asked earlier about my brother. Don't bother looking for him, Elena. I killed him last night.† Her head jerked up, but there was nothing to see, only the dizzying whiteness, which burned her nose and cheeks and clogged her eyelashes. It was only then, as the fine grains settled on her skin, that she realized what they were: snowflakes. It was snowing on the first of November. Overhead, the sun was gone.

Hsc Art Case Study. Marcel Duchamp Essay examples

â€Å"The Duchampian Influence† Marcel Duchamp. In 1913 a French artist mounted a bicycle wheel on a stool, and changed the art world forever. Duchamp is arguably the most influential artist of the twenty-century, his influence is not always obvious or dominate however the underlying acceptance of radical freedom of action and thought that is concurrent in artists practice can always be traced back to Duchamp. Duchamp was a French artist who was a part of the Dada movement, a modern art movement based around the idea of challenging the norm. Dada was anti-art, it was more a â€Å"world view† rather then a distinct style, going against conventional art the aim being to provoke, stimulate and involve the audience (even if that involvement was by†¦show more content†¦In mocking the seriousness of that ambitious art, Rauschenberg predicted an attitude more widespread among later generations of artists. Bed is as personal as a self-portrait, a quality consistent with Rauschenbergs statement, Painting relates to both art and life†¦I try to act in that gap between the two. Although the materials here come from a bed, and are arranged like one, Rauschenberg has hung them on the wall, like a work of art. So the bed loses its function, but not its associations with sleep, dreams, illness, sex—the most intimate moments in life. Critics have also projected onto the fluid-drenched fabric connotations of violence and morbidity. Bed is multi-layered artwork; in a Duchampian way he challenged traditional conventional aesthetic and methods. Rauschenberg treats the materials with a certain respect while he integrates the objects (pillow, bed sheets and quilt) with the paint evoking the past life of the objects. Rauschenberg gives new life from the old. Much like Duchamp’s Readymades; Rauschenberg’s Combines challenged the â€Å"notion of originality†. Even in contemporary art, audiences have difficulty accepting found objects/readymades that the artist themselves have not originally made (for example Jeff Koons’s work) as art. Yet without Duchamp setting the past precedent with his readymades the work of Rauschenberg would be â€Å"unimaginable†. Duchamp’s readymades where selected objects that
