A EXAMPLE OF THE SPC

NOW WE WILL EXPLAIN THE EXAMPLE WITH «NELSON RULES»

AS CAN THE VERSE IN THE GRAPH, FIND POINTS THAT MEET THE CHARACTERISTICS NELSON RULES 5, 6 AND 7.

Nelson rule 5. Two or three (out of three) points in a row are more than two standard deviations from the mean in the same direction.

Nelson rule 6. Four (or five) out of five points in a row are more than one standard deviation from the mean in the same direction.

Nelson rule 7. Fifteen points in a row are all within one standard deviation of the mean on either side of the mean.

PERSONAL CONCLUSION

IN THIS EXAMPLE WE USE THE «NELSON RULES» FOR WE SHOULD DISCUSS THE PROCESS TO DETERMINE WHY OF VARIABLES IN THE SAMPLING, WE NEED NELSON RULES TO IDENTIFY THE PRODUCTION ERRORS.
