WebIn this case, the larger the standard deviation is, the lower the quality of your manufacturing process. This is regardless of the actual standards you need to meet - if process A has higher standard deviation than process B, than for any tolerance interval $\pm a$ mm, process A will generate more bad products than process B. WebThis result tells you that your standard deviation is 2.3% of the mean of 4.4, which is pretty small. In other words, the data is tightly clustered around the mean. On the other hand, if your percentage was large, say, 55%–this would indicate your data is more spread out.

Web25 mei 2024 · Standard deviation is a number used to tell how measurements for a group are spread out from the average (mean or expected value). A low standard deviation means that most of the numbers are close to the average, while a high standard deviation means that the numbers are more spread out. WebStandard deviation has the same units as the mean, M, and we can use both values to find probabilities for a normal distribution.
