Statistical Process Control 100% PASSED

SPC is based on __________ - ANS samples how close measurements are to each other - ANS precision how close a measurement is to the true value - ANS accuracy - can be described completely by knowing only the mean, and standard deviation - The area under sections of the curve can be used to estimate the cumulative probability of a certain "event" occurring - ANS properties of a normal distribution Usually, we set control limits of __________ - ANS +/- 3 standard deviations - Every process has random variation in it. - Production processes are not usually found in a "state of control" - ANS Basic assumptions (tenets) of Process Quality Control When a process is stable and predictable, it's ___________ - ANS in a "State of Control" We take samples, calculate control limits, look for outliers (indicators of assignable cause variation), look for root causes, and fix them - ANS Performing Statistical Process Control (SPC) A line in a control chart that provides the largest value that is still acceptable without being labeled an abnormal variation. - ANS Upper Control Limit (UCL) A line in a control chart that provides the smallest value that is still acceptable without being labeled an abnormal variation - ANS Lower Control Limit (LCL)
