Can stdev be negative
WebSTDEV assumes that its arguments are a sample of the population. If your data represents the entire population, then compute the standard deviation using STDEVP. The standard deviation is calculated using the "n-1" method. Arguments can either be numbers or names, arrays, or references that contain numbers. WebIf all the observations are exactly equal, then the standard deviation is exactly 0. So, the standard deviation can be 0 or greater than zero always. Hence, the standard deviation …

The concept that a negative value appears come from a … WebInterestingly, standard deviation cannot be negative. A standard deviation close to 0 0 indicates that the data points tend to be close to the mean (shown by the dotted line). The further the data points are from the mean, the greater the standard deviation.

The symbol for standard deviation is sigma, σ. The equation for standard deviation is σ = ∑ ( x i − μ) 2 N. The variance is equal to σ 2. Standard deviation is used for data sets that follow a normal distribution.
WebSince symbol √ always means non-negative square root then SD cannot be negative. The content of the Explain section then is irrelevant. In fact, it explains why variance cannot be negative which is a different question after all. Webstdev computes the standard deviation of the values in x.
