What Does 1 Sigma Mean in Statistics? Understanding Standard Deviation

Learn what 1 sigma means in statistics and how it relates to data variation and quality control in a normal distribution.

0 views

1 sigma refers to a statistical measure indicating a deviation from the mean. In a normal distribution, it means approximately 68.27% of the data points fall within one standard deviation of the mean. This concept is commonly used in quality control and process improvement to understand variation and performance.
