{"Image DocumentName": "Advantage of SDAssume the mean is 10.0, and standard deviation is 3.36.", "Image ImageDescription": "one standard deviation above the mean is and one standard deviation below the mean is The standard deviation takes account of all of the scores and provides a sensitive measure of dispersion. it also has the advantage that it describes the spread of scores in a normal distribution with great precision. The most obvious disadvantage of the standard deviation is that it is much harder to work out than the other measures of dispersion like rank and percentiles.", "Image XResolution": "37", "Image YResolution": "37", "Image ResolutionUnit": "Pixels/Centimeter", "Image Software": "SlidePlayer", "Image YCbCrPositioning": "Centered"}
