Similarly the first quartile can be defined as 1/4 of the way through the sorted data, and the triad quartile to be 3/4 of the way through the sorted data. Second quartile is also known as the median. The range between the first and third quartiles includes half(a) of the data. The size of the range (i.e., the difference between the third quartile and the first quartile) is another measurement of divergence called the inter-quartile range or IQR. For normally distributed data IQR = 1.35 From the above calculations it appears the reorganization exercise has not been a grand success. though it appears to have tightened some loose ends but still the average output remains the same.Task-3Table-2 Annual volume of sales revenue & advertising expenditure for SarnesCo (000s)Period123456789101112Sales Revenue cytosine130 one hundred sixty175180xcl190180220250255260Advert ising expenditure1012121213131314151516163 period moving averages for sales A3 = (160+130+100)/3 = 390/3 = 130A4 = (175+160+130)/3 = 465/3 = 155A5 = (180+175+160)/3 = 515/3 = 171.67A6 = (190+180+175)/3 = 545/3 = 181.67A7 = (190+190+180)/3 = 560/3 = 186.67A8 = (180+190+190)/3 = 560/3 = 186.67A9 = (220+180+190)/3 = 590/3 = 196.67A10 = (250+220+180)/3 = 650/3 = 216.67A11 = (255+250+220)/3 = 725/3 = 241.67A12 = (260+255+250)/3 = 765/3 = 2554 period moving averages for sales(it can be calculated similarly as above)A4 = Task-4Task- 5 Business PresentationMaterial for the presentationSarnesCo, the manufacturer of machinery for the material industry, wants to improve its assembly crimpSarnesCo appoints consultant, who in turn study the assembly...The range between the first and third quartiles includes half of the data. The size of the range (i.e., the difference between the third quartile and the first quartile) is another measurement of variability called the inter-quartile range or IQR . For normally distributed dataTaking a look at the mean, median figures of the turnout efficiency before and after the implementation of these steps, it is quite apparent that the consultants have not been able to improve the assembly line as much as desired by the company.
