Figures
1 Typical number-defective chart
2 Number of defectives actually found in consecutive
samples when approximately one defective was
expected per sample
3 Curves showing theoretical probability that m or
more defectives will be found in a sample, for
different values of m
4 To show how sampling from individual production
units can aid judgement
5 Specimen two-way chart
6 Specimen two-way chart demonstrating out-of-control
condition
7 Control chart of assembling galvanized steel
dustbins
8 Control chart of lamination pressings from nickel-
iron strip
9 Two-way control chart of cutting glass plates
10 Compressed limit two-way chart of press tool
operation, examination by gauging
11 Compressed limit two-way chart of weighing plastics
moulded pellets, examination by measurement
12 Interpretation of distributions
Describes the simplest method of statistical quality control by examination for the number of defectives in samples taken from a process that produces individual units of product rather than a continuous product. Accepted methods of charting which are easy to use and may safely and profitably replace 100% routine examinations.
