Smaller spread statistics
WebbIt includes range, standard deviation, quartile deviation, etc. The types of absolute measures of dispersion are: Range: It is simply the difference between the maximum value and the minimum value given in a data set. Example: 1, 3,5, 6, 7 => Range = 7 -1= 6. Variance: Deduct the mean from each data in the set, square each of them and add each ... WebbBox and whisker plots, sometimes known as box plots, are a great chart to use when showing the distribution of data points across a selected measure. These charts display ranges within variables measured. This includes the outliers, the median, the mode, and where the majority of the data points lie in the “box”.

WebbWhen the data has a high SD (e.g., SD = 25), it means that the individual data points are spread out quite a bit. On the other hand, if the data set has a smaller SD (e.g., SD = 0.3), you can infer that the data points are closer to the mean.
