internal consistency calculations were made and it was found that Cronbach's alpha equals 0.848 with lower bound 0.789 and upper bound 0.896 at 95% confidence interval., test versus retest calculations were made as shown in table 8 and Spearman’s correlations coefficients were calculated and represented in table
were asked to supply the postcodes of the children’s main residences. The post code of the state primary school was also recorded. The child’s and the school’s postcode allowed the identification of the Index of Multiplied Deprivation (IMD) score and rank of the school the child attended and the child’s residence. In this study it was hypothesised that children from more socio-economically deprived areas would have more experience of dental caries than children from less deprived areas as measured
and 24.9 Normal Between 25 and 29.9 Overweight Over 30 Obese Correlation: When two or more variables move in sympathy with the other, then they are said to be correlated. If both variables move in the same direction, then they are said to be positively correlated. If the variables move in opposite direction, then they are said to be negatively correlated. If they move haphazardly, then there is no correlation between them. Correlation analysis deals with the following: Measuring the relationship
valid' (Kline 1981, Shackleton and Fletcher, 1984).The Alternative Hypothesis was that there would be a positive correlation between the E and N scores for forms A and B of the EPI. The Null Hypothesis was that there would not be a positive correlation between the scores for forms A and B, and any such found relationship would be down to chance factors operating. The correlation study was carried out because we were looking for a relationship between the E scores and the N scores for forms
source means that I can only make 3 successful hypotheses: * The Older the car the higher the Price Depreciation * The Higher the Mileage the higher the Price Depreciation * The Engine Size would have a very little correlation if any, but if it does the correlation would be, the Bigger the Engine Size the Lower the Price Depreciation To get my primary data I will be using a random sampling. To do this I will use the random button on my calculator. I will pres it twice: first time
and how this relationship changes between girls and boys, with age. I have chosen to investigate the relationship between the height and the weight as I think that the height and the weight are the only two categories that will give a clear correlation. If I was to investigate the relationship of two other categories, like the eye colour and the IQ, I believe that however interesting and amusing the results would be, they would not provide too clear a relationship, or any conclusive information
Bivariate Data Aim The aim of this investigation is to find out whether, in general, more fat means more calories in food. I am doing this to discover which foods' calories are largely composed of fat, and which foods have many calories, and yet have only a small amount of fat, if any at all. The results I discover might be especially useful for people who are dieting. Often people avoid foods with fats in them, and this sort of investigation will help to show what foods are best for
Football Statistics Project Introduction ------------ I have chosen to base my project on football statistics because they are both readily available and interesting enough for deep analysis. As a starting point I decided to look at the generally accepted theory of 'Home Advantage'. Home advantage, or the tendency for the home team to do better than they would away, could have several causes. It could be partly psychological - the home team would almost always have the majority of
This paper is an illustration of quantitative data analysis using the IBM SPSS Statistics software. It does not provide the details of technical skill to operate SPSS but focuses on developing a set of decisions and actions in order to set up, describe, manipulate and analyse data in the specific context of the study of Jackson and Mullarkey (2000). In order to fulfil the task, this paper illustrates a step-by-step of actions that were made on the data. It also gives the insight into the determination
Growing Pleurococcus Aim The aim of this experiment is to find out which side of a tree the most Pleurococcus grows upon, and why this is so. Prediction I think the most Pleurococcus will grow on the North side of the tree. I think this will happen because, the south side of the tree receives the most sunlight. The heat from this sunlight would dry out the Pleurococcus, which would cause it to dry out, and die. As Pleurococcus is an algae, it photosynthesises. This means it needs
Statistical Investigation on Car Prices Data Collection: We are asked to find the relationship between prices of ‘51 registered’ cars and variables such as their current new price, mileage and weight by using the regression analysis. To collect full information of these registered cars, we can access to the websites like: http://www.exchangeandmart.co.ukHowever, in this easy, we use the data, which are provided with the assignment by our teachers. By the sources, 100 cars, which
The Impact of Entrepreneurial Characteristics on SME Performance The Small and Medium Enterprises (SME) plays a very important role in the success & development of any economy. According to the SME policy 2007, “SME sector is the backbone of Pakistan’s Economy”. Globally, this sector is the major growing force behind the fastest growing economy of China, in term of contribution to the national GDP, scale of assets, diversification of products and the creation of employment. Similarly, the role
measure patients satisfaction. To test the CWEQ-II scale, Cronbach’s coefficient alpha was used. The result of the CWEQ-II alpha was .778. Cronbach’s alpha acceptable values were from .803 to .851. Using the conduct validity the results was acceptable. Pearson’s product-moment correlation coefficient was used to compute the patient’s satisfaction in relation to nurse’s empowerment. The result showed positive significant correlation between the score from CWEQ-II and Press Ganey Overall Satisfaction
A Study of the Changes in River Processes This is a study of the changes in river processes along the long profile of a river. To study this we will use a sample river. The river the study will be based on Loughton Brook, which is a river situated in Epping Forest in Essex and is also a tributary of the river Thames. A journey will be made to the river and measurements will be made at three different sites. The measurements that were taken will be studied so conclusions

(2000). Participants had to rate their academic performance in a particular area such alertness, participation, attention, mood, taking note and the level of anxiety before test. The survey also asked the Cumulative Grade Point Average to find the correlation between breakfast and academic achievement of students. The results found that breakfast eater correlated with mood and note taking in the class and students who took breakfast more likely to have good rate in CGPA. SPSS have been used to analyze

different categories. We have measured correlation between the achievement motivation score in the respective categories and the CGPA. Further we have studied the relation between aggregate achievement motivation score and the CGPA. We have also taken into consideration the role of gender in our study. REVIEW OF LITERATURE Many researches have been conducted to investigate what motivates students for better academic performance and whether it has a correlation with achievement motivation. In
households. With that being said, couples do not just decide to get a divorce for no particular reason. There must be something driving them towards marital dissatisfaction and further, driving them towards divorce. Background Information The correlation of divorce and unemployment rates or the relationship between marital satisfaction and employment status have relevance to anyone interested or affected by a marriage. This includes married couples, children, relatives, family friends, psychologists
questions: 1. Does homework performance have a direct correlation to student academic performance? 2. What strategies can result in improvement in student homework performance? 3. Will these strategies have a measurable impact on student performance on: a) Homework? b) Classwork? c) Classroom tests? d) Year-end Standardized testing? This literature review will focus on these three questions. Does homework performance have a direct correlation to student academic performance? According to the
