WebMar 10, 2024 · 4. Multiply your decimal value by 100. To determine your total defect rate, multiply the previous step's quotient by 100. Multiplying by 100 creates the percentage, which is your total defect rate. You can compare your defect rate to previous calculations to determine if any significant production changes occur. WebJan 10, 2024 · To calculate a confidence interval (two-sided), you need to follow these steps: Let's say the sample size is 100. Find the mean value of your sample. Assume it's 3. Determine the standard deviation of the sample. Let's say it's 0.5. Choose the confidence level. The most common confidence level is 95%.
