Can stdev be negative
WebDec 18, 2024 · No, the value associated with the standard deviation cannot take on a negative value. This is apparent by examining the formula for the standard deviation itself. All the individual values in a dataset (xi ) have a value for the mean (¯x ) subtracted from them. This can result in either a positive or negative value. Is the mean always positive? 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.
