The range of standard deviation values depends on the dataset. For a given set of data, the standard deviation is always a non-negative value (it cannot be negative). The standard deviation value can range from 0 to infinity.
0: Indicates no variability (all data points are the same).
Infinity: In theory, if data points are extremely spread out, the standard deviation can be very large, approaching infinity.
In practical terms, standard deviation values are specific to the dataset being analysed. get free Demo class online contact today at Durga Online Trainer
