Purpоse: Awаreness оf аpplicаtiоn of Statistical Methods One of the most important tasks of quality control in manufacturing is to make sure products meet their specifications. In the past, quality control inspectors rejected defective parts during a 100% inspection of the product. This would be a huge potential cost and it is advisable to determine instead if there is trend in defects and to correct the process before producing defective parts. Statistical Process Control is a method that replaces 100% inspection by suing statistical analysis of the measurements taken from a few random samples of the total product's run. Examine the following application: You are a machine operator at a small manufacturer of engine parts. A machine that produces spacers has just been installed in the plant and you have been asked to test the machine by collecting and producing a histogram of a sample of the parts. During the first shift you measure the parts and collect the following data. Part Thickness (.01mm) 25 45 41 52 45 37 58 46 43 26 41 50 48 50 54 43 52 33 38 44 52 48 51 48 47 48 56 61 34 39 47 34 37 42 55 59 49 57 35 53 61 40 64 45 44 38 47 42 28 32 NOTE_ - above data has been coded. the actual part thickness is 4.0mm plus the value listed in the chart (e.g. the first value is actually 4.25mm). Eliminating the decimal points whenever possible makes the calculations neater and easier to work with. The data shows "Part Thickness (0.01 mm)" Answer the following questions: a) What is the range of this data? b) Use 6 to 8 classes to draw a histogram of the data c) How would you describe the shape of the data? d) Based on your answer to part c) what measures of center and spread would best describe the data.
