particularly in developed economies. TQM has evolved primarily because of the changes in the global economy and also because of demand in market forces. Although control of quality has been practised in many industries for several years, the adoption of TQM as a major preoccupation of businesses worldwide is very recent. The traditional control methods being implemented in industries to ensure quality have not yielded the results that were expected of them. Furthermore, rapidly changing technology

design, although it might be based on qualitative and quantitative methods’ tools and theories. Quantitative research methods include many particular techniques and in general could be described as methods, which works with numbers and applies statistical analysis by using various mathematical operations with formulas and computer software. The usage of surveys and various types of databases are examples of quantitative methods. Scientists conduct surveys either in person, or through telephones,

Carl Frederick Gauss (1777-1885) who introduced the concept of normal curve. Six Sigma as a measurement standard in product variation can be traced back to the 1920´s when Walter Shewhart showed that three sigma, from the mean is the point where a process requires correction. As history would seem to have it, the beginnings of Six Sigma really come from 1979 when an exasperated Motorola executive named Art Sundry said, at a meeting, “The real problem at Motorola is that our quality stinks!”. Apparently

for patterns within particular datasets. Inferential statistics requires drawing conclusions in predicting future numbers based on sample data. With both types of statistics, businesses are able to better manage, process, and predict trends in many different business processes. Statistical Methods In statistics, there are several types of methods including experimental, observational, levels of measurement, and null hypothesis (Washington, 2002). In the experimental method, causality is determined
