Q

used to study how a process changes over time

A

Control Charts

24
Q

Control Charts Composed of:

A

– Central Line
– Upper Line for the UCL
– Lower Line for the LCL

25
Q

Control Charts Can conclude if variation is

A

– CONSISTENT (in-control)
– UNPREDICTABLE (out of control)

26
Q

How to Construct a Control Chart

A
  • Determine the mean, UCL and LCL.
  • Estimate an arbitrary range (with same interval).
  • Draw the lines.
  • Plot the data.
    – Number of sample (X-axis)
    – Sample Weight (Y-axis)
  • Interpret the results.
    – Out-of-control signals
27
Q
