WebbWhat is standard deviation value? The standard deviation is the average amount of variability in your dataset. It tells you, on average, how far each value lies from the mean. A high standard deviation means that values are generally far from the mean, while a low standard deviation indicates that values are clustered close to the mean. WebbRelative standard deviation (RSD) is a special form of the standard deviation. It is obtained by multiplying standard deviation with 100 and dividing by mean. 2. How do you explain relative standard deviation? Relative standard deviation is used to determine if the standard deviation of a set of data is large or small when compared to the mean.
