significant influences on the business cycle. This paper tries to figure out the determinants of the selling price of houses in Oregon. The data set used in this paper has been retrieved from the case study titled “Housing Price” (Case #27 - Practical Data Analysis: Case Studies in Business Statistics- Marlene A. Smith & Peter G. Bryant) The most important factor in determining the selling prices ofhouses is to know the features that drive the selling prices of the house. People tend to have more interest

Testing statistical significance is an excellent way to identify probably relevance between a total data set mean/sigma and a smaller sample data set mean/sigma‚ otherwise known as a population mean/sigma and sample data set mean/sigma. This classification of testing is also very useful in proving probable relevance between data samples. Although testing statistical significance is not a 100% fool proof‚ if testing to the 95% probability on two data sets the statistical probability is .25% chance

According to the theory of exploratory data analysis which published by John Tukey‚ for analysing unstructured data‚ statistical analysis should focus on exploring phenomena behind models (Tukey‚ 1992). Thus‚ apart from testing the model by software‚ factors will be analysed and discussed by the contrastive or cross-over analysis approaches to weight the importance of them. Subjective Norm As a theoretical foundation of TAM2‚ Subjective

Statistical process control (SPC) is the application of statistical methods to the monitoring and control of a process to ensure that it operates at its full potential to produce conforming product. Under SPC‚ a process behaves predictably to produce as much conforming product as possible with the least possible waste. While SPC has been applied most frequently to controlling manufacturing lines‚ it applies equally well to any process with a measurable output. Key tools in SPC are control charts

Statistical Quality Control (SQC) is a set of statistical techniques intended to aid in the improvement of system quality.[i] DEFINITION The Statistical Control of Quality is application of statistical principles and techniques in all stages of design‚ production‚ maintenance and service. The phrase “statistical quality control” (SQC) refers to the application of statistical methods to monitor and evaluate systems and to determine whether

A researcher predicts that watching a film on institutionalization will change students’ attitudes about chronically mentally ill patients. The researcher randomly selects a class of 36 students‚ shows them the film‚ and gives them a questionnaire about their attitudes. The mean score on the questionnaire for these 36 students is 70. The score for a similar class of students who did not see the film is 75. The standard deviation is 12. Using the five steps of hypothesis testing and the 5% significance
