Statistical Process Control 100% PASSED
Get a hint
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)
