Lecture: Contingency Tables Anderson Example: Quality Problems A company that manufactures cardboard boxes is trying to understand some of their quality problems. They decide to collect data on defect type (Printing, Color, and Skewness (how square the box is)) and the shift during which production occurred (first (1), second (2), or third (3)). The data (sorted by defect type) is: Defect Create a 1-way contingency table for Defect type type Shift Defect Type f Color 1 Color Color N Color Print Color NWWH Skew Color Color Total Color Color Color Create a 1-way contingency table for Shift Color Shift Color 1 Color 2 Color Color 3 Color Print Total Print -NW Print Create a 2 way contingency table. Print Print Total Print Print NNHWAN Print 11 Print Print Print Print NNPNP Print Total Skew Skew What is the total number of observations collected? How many errors were on Shift 1? How many Printing errors did Shift 3 make?Create the %f total table and the %f independent variable contingency tables.
