emined for? The PDCA cycle 3 Multiple Choice for SPC Total 10 points 1- When you test the quality of Al-Ain road by tracking 30 road segments of varying distance and recording the number of imperfection in each selected segment, what control chart will you use? Why? Consider a firm that has decided to use a control chart to help keep track of the number of complaints received daily on a given product. Over a 30 days period, 600 complaints are received. What are the limits of the control chart? conplas alod 2- (2 points are appropriate. (1 point) 3- In a situation where it is Not possible to draw samples,,Explanation / Answer
Sol: 1) Here, the road length for each sample is different and so, the absolute no. of defects recorded cannot be compared across the samples. Instead, the no. of defects per unit length of sample road for the 30 samples makes more sense. So, our attribute is no. of defects for unit road length for a sample of 30 road degments of varying lengths.
We must use 'u' control chart in such a scenario. The u-chart is a type of control chart used to monitor "count"-type data where the sample size is greater than one, typically the average number of nonconformities per unit. The u-chart differs from the c-chart in that it accounts for the possibility that the number or size of inspection units for which nonconformities are to be counted may vary.
