As such, the formula for standard deviation is: Such that: σ = the … WebStandard Deviation – Standard Deviation (SD) is a statistical term used to describe how close or far away a specific score is from the mean (average of 100 on the BDI-2). Standard deviation on the BDI-2 is measured in terms of 1 standard deviation = 15; therefore a score of 85 is considered 1 SD below the mean and a score of 115 is

While the mean identifies a central value in the distribution, it does not indicate how far the data points fall from the center. Higher SD values signify that more data points are further away from the mean. In other words, extreme values occur more frequently. … See more Suppose two pizza restaurants advertise a 20-minute average delivery time. We’re starving and both look equally good!
