What is the difference between variance and standard deviation?
Opportunities and Realistic Risks
Not correct! Standard deviation can be applied to both quantitative and qualitative data, although the interpretation may vary.
Actually, standard deviation can be positive or negative, depending on the dataset.
Standard deviation is a measure of the amount of variation or dispersion from the average value. It represents how spread out the values are from the mean value. Imagine a set of exam scores: if the scores are close to the mean, the standard deviation will be low, indicating a narrow range. Conversely, if the scores are spread out, the standard deviation will be high, indicating a wider range.
Standard deviation is only used for quantitative data
