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
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
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
Is Beauty the Key to a Better Life?
Shawna Danielson Kellie Clemmer Psych 1110 23 February 2009 Is Beauty the Key to a Better Life? . What am I being asked to believe or accept? Attractiveness plays an important role in whether or not an individual will be successful- both at home and in the workplace. Some individuals argue that attractiveness can hinder a persons chance for a successful relationship and can belittle their talents and intelligence. Others argue that attractiveness can improve an individual's chances of having a happy, successful relationship, and that beautiful people earn more, live longer, and have better lives. 2. What evidence is there to support the assertion? Our American culture looks to a women's body, and physical appearance, as a way of determining femininity (Kalof, 1999). There is evidence that suggests that physical attractiveness influences others perceptions and evaluation, treatment afforded by others, and overt behavior and self-perception. This occurs throughout an individual's lifespan, in both men and women, and in other cultures as well (Baron, Markman, & Bollinger, 2006). For centuries, beauty has been equated with having positive qualities. Beautiful people are perceived as having elegant homes, expensive cars, and successful lives. They are also expected to be healthy, wealthy, ad wise (Van Leeuwen & Macrae, 2004). They are also perceived as being more
The comparison of antibacterial properties of herbal products and standard antibiotics
The comparison of antibacterial properties of herbal products and standard antibiotics Introduction: This is As biology coursework, studying the area of microbiology the main investigation contains the comparison of antibacterial properties of herbal products and standard antibiotics. Aim: The aim is to investigate the effect of herbal products against standard antibiotics on bacteria growth. To examine the extent to which the herbal products (tea tree oil and peppermint oil) and the standard antibiotics (penicillin and streptomycin), reduce bacteria growth of E.coli and M.luteus. This will be discovered by measuring the growth of bacteria on the agar plates and comparing the results. Background information: The proposed aim surrounds the study of bacteria growth and various other products, which can have an affect on the growth rate; it is therefore necessary to look deeper into the topic criteria to get a wider understanding and to help design an appropriate hypothesis. From self-knowledge antibiotics are chemicals produced by microorganisms, which are designed to inhibit and destroy specific pathogens when used at low temperatures. Antibiotics release chemicals, which inhibit bacterial growth and work on a specific action site. The first founded antibiotic was penicillin discovered accidentally by Alexander Fleming in 1928 from a mold culture. It can be
Outline and evaluate one Social Learning Theory explanation of personality development
Outline and evaluate one Social Learning Theory explanation of personality development Bandura believed that an individual's personality was developed as a result of interaction between the individual and their environment. He called this interaction reciprocal determinism, and suggested that people play an active role in determining their behaviour in an environment: they will behave in a certain way that is appropriate for the setting that they are in, but their behaviour may also change that setting. This, according to Bandura's social-cognitive theory, occurs by means of a process of observation and imitation, known as modelling. Modelling is spontaneous and requires no deliberate effort on the part of the learner or the model (the person whose behaviour is to be observed and imitated), and reinforcement is not necessary for such learning to occur. This means that the study explains what the Behaviourist explanation of behaviour could not: the ability to produce or reproduce behaviour without reinforcement. However, although unnecessary, reinforcement will affect the performance of the behaviour; this is known as vicarious reinforcement. Bandura's theory incorporates cognitive factors into its explanation, and for a model's behaviour to be imitated, there must be some internal mental representation of the model. There are five steps to the modelling process. The first
Evaluate the strategies that a business can adopt during a recession
Evaluate the strategies that a business can adopt during a recession A recession, two negative quarters of GDP in an economy, is inevitably going to lead to a business getting less customers. Its overhead costs will be the same, but its unit costs will be higher because it will not be producing as many products but will still have these fixed costs. This will make the business less profitable in the short-term and so strategies must be implemented to try to improve the business's short-term and long-term prosperity. Such strategies might include improving its cash flow position, downsizing, decreasing its costs, decreasing its gearing and managing its receivables and payables more carefully. A strategy of improving cash flow will involve many aspects. They will need to decrease their fixed costs so that their unit costs will decrease and it will be easier to make a profit in the difficult economic climate. This may involve selling off excess machinery or ordering less inventories, or it may involve increasing its operational efficiency by holding less inventories and thus lowering its storage costs. Ultimately, improving its cash flow will enable the business to remain more liquid in hard times, where investors (e.g. banks) will be less financially lenient, in the way of loaning money to businesses, during a recession. Thus it is more crucial than ever for a business to
Law of Evidence - R v Kearley
Law of Evidence - Assessed Work (No.2) by Simon Wolman R v Kearley Essentially this piece concerns whether the House of Lords correctly decided the case of R v Kearley1. The majority decided allowing the appeal, that the evidence concerned in this case was either irrelevant, and therefore inadmissible (unless part of the res gestae) or was inadmissible as hearsay in the form of an implied assertion. The facts of Kearley will be discussed, followed by an analysis of the decision by their Lordships, finally considering the issues of relevance and implied assertions in relation to the decision in Kearley. The facts of Kearley are well known. The disputed evidence was that the police officers whilst on the raid answered a number of callers to the flats, both by telephone and by visitors. The police officers testified that the callers were seeking to buy drugs in place of the original callers who were unwilling or unable to attend court. The appellant objected to the evidence on the ground that it was hearsay, but this was overruled. The Court of Appeal dismissed his appeal and certified a question to the House of Lords. Condensing the certified question, it was whether a person not called as a witness, for the purpose of not establishing the truth of any fact narrated by the words, but of inviting the jury to draw an inference from the fact that the words were spoken ? 2 On
