A standard deviation is so "standardized" that, generally speaking, 70% of the data points will fall within one standard deviation, and 90% of the data points will fall within two standard deviations. Standard deviation is one of the most common way Continue Reading...
median and the mode. The mean is the average of the total set, the median is the middle of the total set and the mode is the most frequently reported number of the total set. The median can be found by literally writing the numbers in a string, and Continue Reading...
When the examples are spread apart and the bell curve is relatively flat, that tells you there is a relatively large standard deviation (Niles). The average deviation is the absolute value of the difference from the mean for each data value, summed Continue Reading...

Important measures in data summarization include measures of central tendency (i.e. "averages" or the mean, median, and/or mode) and measures of dispersion or variability -- the range of the data and the standard deviation of the points within the d Continue Reading...
Probability Probabilities according to Becker and Parker (2011) are used in both simulations and real life scenarios to help in the estimation of the occurrence of events. In the words of Gravetter and Wallnau (2008), "for a situation in which sever Continue Reading...
