To what extent will does correlation and extrapolation assist Nintendo in forecasting sales?
To what extent will does correlation and extrapolation assist Nintendo in forecasting sales? (34 marks) Correlation is the relationship between two variables. Extrapolation is related to correlation, as it involves plotting a linear regression curve (also known as a line of best fit) which is based upon how two variables are correlated, and extending the line to predict future values. For Nintendo, a computer game and console manufacturing company, a common example would be the relationship between the level of advertising expenditure and the effect of this on sales of its products. The graph to the left shows a strong positive correlation between sales and advertising, meaning if Nintendo increases its advertising, they can expect to see an increase in sales. Because all values are close to the line, as advertising expenditure increases on the x-axis, sales on the y-axis increase proportionately. The regression line can be extended past the '80' figure (meaning £80million) to predict what sales will be like if they spend £100million or even £900million. The uses of such analysis to Nintendo are to an extent very valuable. By creating a scatter graph like the one above, Nintendo can spot trends and forecast future events. For example, they could estimate demand at a certain point in the coming year. One would expect demand to surge at Christmas time when people are
Explain why the depression of 1929 was a godsend for the Nazi Party
Explain why the depression of 1929 was a 'godsend' for the Nazi Party Of all European countries, none was hit harder than Germany by the stock market crash of October 1929. Germany, who was still suffering from the Treaty of Versailles, had borrowed very large sums from American banks, with much of the money repayable either on demand or at short notice. These loans were of course recalled, and bankruptcies in Germany rose sharply from the start of 1930. Unemployment rose sharply, too. The German economy plummeted with the stock market and the situation Germany found itself in resulted in even more faith being lost in the Weimar constitution. This situation was a godsend for the Nazi Party as it enabled them to gain public support. Having lost faith in what they already felt was an indecisive Government, and after the 'stab in the back' myth having been circulated throughout the country, Germany became increasingly hard to govern. Hitler, an inspiring and energetic speaker, took this opportunity to present himself and the Nazi party to the German people. Showing himself as a strong leader, he promised to abolish the Treaty of Versailles and restore Germany to power. This was one of the ways in which the Great Depression aided the Nazis. Because of the people of Germany falling into poverty and despair and being eager for help, Hitler's talk of a new Germany and his

Biology Coursework To determine if the distribution of flora across Ellerbeck is due to chance. The valley containing Eller beck possesses a huge variety of different species of plant life, particular species are often found in specific places across the valley, to find out why these particular plants grow in the particular places I mean to investigate where different species of plants are located and what the conditions in those particular places are, investigating the effects of several factors on the distribution of these different species across a specific area of the valley. I believe that the varied distribution of the different species investigated is directly related to, and can be explained by the differences in the factors I will be measuring, that certain plants will grow in certain places in the area because they are more suitably adapted, in whatever way to the conditions in that specific place. This is a rough diagram of Ellerbeck. I plan to perform my investigation using two information gathering techniques, after first establishing a straight line across the valley by taking a bearing using a compass from one point at the top of the South side of the valley and following that bearing down the valley, across the beck and up the other side whilst performing both a line transect and an interrupted belt transect. I also plan to perform an interrupted belt
Explain how twin and adoption studies attempt to distinguish genetic and environmental factors underlying the onset of schizophrenia within families. Review the studies and discuss two limitations of this.
Psychology Essay Explain how twin and adoption studies attempt to distinguish genetic and environmental factors underlying the onset of schizophrenia within families. Review the studies and discuss two limitations of this. Schizophrenia is the label applied to a group of disorders characterised by severe personality disorganisation, distortion of reality, and an inability to function in daily life. Symptoms are mainly disturbances of thought processes, but also extend to disturbances of emotion and behaviour. There are two symptom categories - acute schizophrenia characterised by positive symptoms, such as hallucinations and delusions; and chronic schizophrenia, characterised by negative symptoms such as apathy and withdrawal. However, DSM-IV has now moved away from these definitions and classified schizophrenia into three main sub-types: paranoid, disorganised and catatonic. Understanding Schizophrenia More research has, probably, been devoted to trying to understand the nature of schizophrenia than any other mental disorder. Somatogenic approaches have focused on the role of genetic mechanisms influencing the propensity to develop schizophrenia, while psychogenic approaches emphasise the effect of adverse childhood experiences, particularly abnormalities in family interaction in the aetiology of the disorder. Twin studies Twin studies offer a
Tennessee Williams wrote in a letter that It (Streetcar) is a tragedy with the classic aim of producing a catharsis of pity and terror and in order to do that, Blanche must finally have the understanding and compass
Tennessee Williams wrote in a letter that "It ('Streetcar') is a tragedy with the classic aim of producing a catharsis of pity and terror and in order to do that, Blanche must finally have the understanding and compassion of the audience. This without creating a black-dyed villain in Stanley. It is a thing (misunderstanding) not a person (Stanley) that destroys her in the end." In your opinion, to what extent has Williams succeeded in his aims. Although there are many different viewpoints on a conventional tragic heroine, Aristotle made his views clear that a hero must fall from fortune and power, due to a tragic flaw, allowing an audience to feel catharsis at the end of the play. It can be argued that Stanley causes Blanche's downfall, however, it is clear that Blanche had brought this upon herself by creating a conflict between them and ensures her own downfall by other means such as her promiscuity and flux into fantasies. Williams makes it clear that a misunderstanding destroys Blanche in the end. This misjudgement can be seen in her aggressive teasing of Stanley and her uncomfortable belonging in multi-cultural New Orleans. From the beginning of the play, Williams makes it clear that 'the Kowalski and the DuBois have different notions' with Blanche withholding the Southern Belle attitude of 'Belle Reve'. However, it is clear that Blanche cannot cope with the stark
Was Nicholas II responsible for his own downfall?
Was Nicholas II responsible for his own downfall? Nicholas II acted as an autocratic monarch rather than a constitutional leader, and this was a factor in his eventual downfall and abdication. Other factors included, him leaving Russia in the incapable hand of his wife, Alexandra, who herself was greatly influenced by Rasputin. The 'Holy Man' Rasputin was becoming more and more popular with Alexandra for helping their only son, Alexis's with his haemophilia, and his strange but powerful brand of spirituality certainly affected both Alexandra and Nicholas. It could be argued that Nicholas was himself responsible for allowing the power of Rasputin to extend so far and to influence his political decisions. Historians are in agreement that Nicholas lacked the necessary skills and qualities to rule a rapidly changing country. There were however factors outside of Nicholas' control, including his son's illness, that he could not be held directly responsible for. Indeed Russia was a huge country which was very hard to govern even for the most competent Tsar. One of the first factors which Nicholas was responsible for was his weak character and the fact that he allowed Alexandra to be so dominant. She encouraged him to hold on to his absolute power when a change in his style of leadership may have been a more politically useful tactic. A very significant contributing
Relating the structure and function of cell organelles
Relate the structure and function of cell organelles Cells are like cities with intricate organelles 'living and working' in it. There are basically two kinds of cells, namely Prokaryotic and Eukaryotic. Both plant cells and animal cells are eukaryotic while prokaryotic cells are simplier organisms that possess non-membrane bounded organelles. In most cells they contains the following organelles which carry out unique functions and allow cells to work properly. To start off with, nucleus is a large roundish organelle enclosed by a double membrane with numerous openings, namely nuclear pores, for nuclear traffic. It contains chromosomes and one or more nucleoli. Nucleolus is a spherical site where ribosomes are formed. Chromosomes contain DNA which tends to be packed in form of chromatin. Only during interphrase (a stage before a cell divides in a cell division process), chromosomes will be unravelled for easier replication. Tiny, hollow cylinders of protein called centrioles form a network of spindle fibres in the nucleus during nuclear division to pull chromosomes apart. The inner membrane of nucleus will break down and allow chromosomes lying freely in cytoplasm. DNA contains the genetic information and control the synthesis of protein. Each cell contains millions of ribosomes. They are very tiny, non-membrane bounded organelles made of protein and RNA which consist of
Outline and evaluate research into obedience (12)
Outline and evaluate research into obedience (12) In Milgram's original obedience to authority study, his aims were to set up a situation in which single individuals were ordered to act against a stranger in an inhumane way and to see at what point they would refuse to obey the order. Milgram advertised for male volunteers by placing an advert in a local paper, which offered $4.50 as payment for taking part in a study of 'punishment and learning'. 40 respondents from a range of backgrounds were selected and were told to attend the laboratory in Yale University. They were greeted by the experimenter, and were introduced to a 'supposedly' participant, Mr Wallace, but actually he was a confederate. They were both experienced to a role-assignment but it was rigged so that the real participant was the teacher. The experimenter explained to the teacher that it was his job to teach the learner a series of word pairs and then test their recall. If an error was made in the answer, an electric shock was made, starting from 15V working upwards each time. As the shocks became higher, the learner screamed and became more dramatic, and complained of a weak heart at around 180V. The participants showed signs of extreme tension, even showing nervous laughing fits, but they were still told to 'please go on' even though they didn't want to continue. Along side that, when the teacher refused
Outline the development of attachments
Developmental Psychology - Key Assessment Task a) Outline the development of attachments An attachment is a powerful bond between an infant and its caregiver. Infants form attachments because they are helpless at birth and so need caregivers to provide for and protect them. There are many long term effects of attachments, for example an attachment gives a foundation for emotional relationships e.g. the infant is learning how to form an emotional or "love" relationship. Schaffer and Emerson believed that infants form attachments by three stages, this argument was based on a large scale study of 60 infants in a working class area of Glasgow over 2 years. The first stage of attachment Schaffer and Emerson believed a child to go through happens when they are 0-6 weeks old, this is known as the Asocial Stage and involves the infant smiling and crying but not directing these emotions at individuals. The second stage of attachment is known as Indiscriminate Attachment and happens when the infant is 6 weeks to 7 months old; this involves the child seeking attention from different individuals. The last stage of attachment is Specific Attachments and happens when the infant is 7-11 months old, this stage shows a strong attachment to one individual, with good attachment to others following afterwards. b) Describe the procedures and findings of one study of individual difference in
How does Sujata Bhatt show that identity is important in from Search For My Tongue? Compare the methods she uses with the methods another poet uses to show that identity is important in one other poem.
How does Sujata Bhatt show that identity is important in 'from Search For My Tongue'? Compare the methods she uses with the methods another poet uses to show that identity is important in one other poem. 'Search For My Tongue' ('SFMT') and 'Hurricanes Hit England' ('HHE') both share a common theme of identity and how it influences our day-to-day life. 'SFMT' and 'HHE' together show show your cultural identity is within you; it's not constricted to a certain place. However, the two poets show this in different ways. In SFMT, Bhatt's emotional response to the language shows its importance. Whereas in HHE, Nichols' final conclusion of 'the earth is the earth' and her response to this epiphany show importance. Language is a method used in both poems to show identity's importance. Both poems use a physical thing metaphorically, too. In SFMT, it's her tongue. Whereas in HHE, it's the hurricane.In SFMT, the two tongues (languages) conflict in her (both physically and metaphorically). The two toungues would be squashed; there's clearly not enough room in someone's mouth for two tongues. This reflects her struggles on knowing two languages: the 'mother tongue' and the 'foreign tongue'. This is effective in showing Bhatt's dilemma and concerns. As a reader, I empathise with her as I understand that it must be difficult and frustrating. Additionally, the metaphor of the language being
