The question: To investigate if there is evidence to suggest that the two operations brick and tile have a difference in accident rates. This type of question involves analysing the data for a difference‚ and so tests such as an equal variance test‚ a normality test and a Mann Whitney test will be undertaken. The meaning and the significance of these tests will be explained and justified later on in the report. Hypothesis Testing: The null hypothesis (Ho) for this investigation is that

ITKM Analysis of Data Mining The article Data Mining by Christopher Clifton analyzed how different types of data mining techniques have been applied in crime detection and different outcomes. Moreover‚ the analysis proposed how the different data mining techniques can be used in detection of different form of frauds. The analysis gave the advantages and disadvantages of using data mining in different operation. The major advantage was that data mining enables analysis of large quantities
