P-chart Control Chart for Defect Rates

I made a mistake! The sample standard deviation is 0.026, not 0.0026 I have been looking around, and can’t find the piece of paper that had my notes on when I made the video. There are two possibilities. 1. I did the math wrong, and didn’t divide before taking the square root 2. I did the math right, but mis-read the decimal place on my piece of paper I hope it was #2, but #1 is also possible. I will re-record the video, but not today ---------- We compute the control limits for a P chart p-bar = average defect rate = total number of defective items, divided by the total number of items sampled n-bar = average sample size s = sample standard deviation UCL = p-bar + 3 * s LCL = p-bar - 3 * s
