WebbA Standard deviation is a statistical tool that measures the volatility of data. It indicates the extent to which sample values deviate from mean values. It is computed as the square root of the variance and represented by the symbol’ σ’ (Greek letter). The standard deviation is usually calculated automatically by whichever software you use for your statistical analysis.
