It includes measures of central tendency, measures of variability, and measures of shape. Of particular interest here are the standardized skewness and standardized kurtosis, which can be used to determine whether the sample comes from a normal distribution. Values of these statistics outside the range of -2 to +2 indicate significant departures from normality, which would tend to invalidate any statistical test regarding the standard deviation. In this case, the standardized skewness value is within the range distribution. expected for data from a normal distribution. The standardized kurtosis value is not within the range expected for data from a normal 12 15 Sugars Stem-and-Leaf Display for Sugars: unit = 1.0 1/2 represents 12.0 01000000001 25 0 | 2223333333333333 31 0| 455555 Histogram (11) 0|66666667777 35 01888889999 26 16 10000011111 1| 22222223333 1144455 15 F The StatAdvisor This display shows a frequency tabulation for Sugars. The range of the data has been divided into S intervals (called stems), each represented by a row of the table. The stems are labeled using one or more leading digits for the data values falling within that interval. On each row, the 12 individual data values are represented by a digit (called a leaf) to the right of the vertical line. This results in a histogram of the data from which you can recover at least two significant digits for each data value. If there are any points lying far away from most of the others (called outside points), they are placed on separate high and low stems. In this case, there are no outside points. Outside points are illustrated graphically on the box-and-whisker plot, which you can access via the list of Graphical Options. The leftmost column of numbers are depths, 9 which give cumulative counts from the top and bottom of the table, stopping at the row which contains the median. frequency 6 -1 3 11 15 Sugars Click on a menu i use button to display documentation.
